Spring Grazing 2016

18 May

At this time last year our cows had been out on pasture for a little over a week.

This year, due to a mild winter, they’ve been out on pasture since April 27th.  They even had 17 acres of winter rye stubble to nibble on before the real grazing kicked off.

160506-IMG_20160506_182322124

And while the weather did open up the opportunity for earlier grazing, it was the three-years of infrastructure that we’ve built (fences, improved pastures, water lines) that have allowed us to capitalize on the early grazing season.

We had our first cow sent to the butcher on April 8th, which seemed a bit optimistic.  Finishing a cow after a Minnesota winter without grain or lush grass seems like a completely impossible task.

Much to my surprise I picked up these ribeyes from the butcher.

160429-IMG_20160429_111524169_HDR

I have no idea how we pulled that off, but those suckers are more marbled than they have any right to be.

Piglet Brooder

15 May

Since we got the new brooder all setup with a propane brooder, we’ve not had need of our old Hover Brooder for the chicks.  But this being Minnesota in the spring, we did have a few cold snaps that left us in need of supplemental heat for our piglets.

160429-IMG_20160429_165701186

All but one of our sows have farrowed (given birth) so far this spring.  The piglets and their mother spend the first three days inside the barn in a farrowing pen.  On or about day three, when the time of greatest danger to the piglets has passed, they’re processed and turned out into group housing with their mothers.

160430-IMG_20160430_104050867

This year we’re using our three-sided pole-barn for community housing for all of our lactating sows. The pole-barn doesn’t have electricity, but it’s close enough (one extension-cord length) to the chicken coop that an electric hover brooder is an option.

The hover brooder for chickens is a pretty good starting place for a piglet brooder, but there are a few important modifications, because pigs.

First up, piglets don’t need to be as warm as chickens.  Chickens need brooder temps of at least 100°F, pigs can get by with 80°F

160427-IMG_20160427_161043172

Since we needed less heat we pulled out two of the five sockets in the chick brooder, leaving us with three sockets in a straight line.  With three bulbs we can go up to 750 watts, but we used smaller bulbs to end up with 375 watts of heat.  That turned out to be plenty to keep the piglets cozy.

The next problem we needed to address was the porcine propensity to play around with absolutely anything they can lay their snouts on.  In a situation where a heat lamp is in proximity to said porcines, the heat lamp bulb will presently meet an untimely end.

Which is to say that piglets will break every heat lamp bulb.
Every. Dang. Time.

Usually snapping the bulb off at the base, leaving it to your friendly neighborhood farmer to painstakingly extract with a pair of needle-nose pliers.

Not cool pigs.

So you see my problem.  Fortunately, I figured that simply covering the bulbs with a bit of 2×4 fence wire would be enough to keep the pesky piglets at bay.

160427-IMG_20160427_163638485

As it turns out I had an even better bit of fence-type-stuff to make a bulb-guard out of.  Once upon a time we had a baby crib that was broken by an overly rambunctious toddler.  This toddlers father, being a connoisseur and collector of choice junk did endeavor to save the wire frame that held up the crib mattress because it looked an awful lot like a heavy-duty bit of 2×4 fencing.  Waste not, want not and all…

And don’t forget the usability considerations, the wire guard needs to swing out of the way for easy bulb changes (heat lamp bulbs have the life expectancy of a mayfly, so there will be lots of bulb changes).  We used three eye screws and three hooks to keep the thing in place.

Little Hoop House on the Prairie

9 May

160502-IMG_20160502_180032779

Look!  We built that.

It’s really not so big of an accomplishment, having now built one I can assert that hoop houses are quite easy to build (relatively speaking).

So without further ado, here is the whole process.

160410-IMG_20160410_154103795

We decided that we’d love to have a semi-mobile hoop house and that required building said hoop house on skids.  Here we’ve got a trio of 4″x6″x14′ timbers (pressure treated, of course) that make up one skid.

The hoop house is a 14′ wide, 36′ long contrapion that we bought from FarmTek.

160410-IMG_20160410_154350258

The FarmTek kit is supposed to be anchored by pounding these big pipes into the ground.  Having chosen skids, this was obviously going to have to change.

160410-IMG_20160410_154326

We chose to drill some big holes (1.75″ holes to be exact) into, but not all the way through, the skids to accept the pipe.  There was just the small matter of cutting off most of the pipe to get rid of the bit that was supposed to go underground.

160415-IMG_20160415_103909875

To make sure it all doesn’t come apart in a stiff breeze, the pipe is “pinned” to the skid with a nice big lag bolt.   The rest of it goes together pretty much according to the instructions.

160413-IMG_20160413_184510554

After looking at the High Tunnel Hoop House Construction Guide [PDF] from University of Illinois Extension, I’m convinced that I could do another hoop house for cheaper, but the FarmTek kit was a pretty nice place to start for a beginner.

160416-IMG_20160416_183415822

The Hoop House Construction Guide got me all adventurous and made me try out a roll-up side.  That ended up being a fantastic decision.

160416-IMG_20160416_182716390

The FarmTek kit pretty much leaves you to finish the ends of the hoop house as you will.  One end of ours got a big window, about 2’x6′.

160416-IMG_20160416_182728504

The other end got the old screen door that used to grace the side of the farmhouse.

160501-IMG_20160501_180152075

After a few days of waiting for the weather to cooperate (winds gusting to 40mph aren’t ideal conditions) we managed to get the greenhouse film stretched over the frame.

160501-IMG_20160501_180255614

The film, which is really a fancy name for 6mil UV-stabilized plastic is held in place by this nifty stuff called “wiggle wire.”  Ripping down 1″ lumber for battens is certainly cheaper than using the aluminum channel and wiggle wire, but the wire gives you the ability to go back and fix any mistakes without ruining the greenhouse film, a hefty advantage to us hoop house n00bs.

160502-IMG_20160502_170028408

No building would be complete without a little sharpie art by the flamboyantly-dressed artist-in-residence.

160502-IMG_20160502_180032779

After skinning the ends with greenhouse film there wasn’t much to do but wait for the first order of chicks to come in.  Fortunately, we didn’t have to wait for long, having had only finished the hoop house a scant 24 hours before the chicks were due to arrive.

160504-IMG_20160504_155625

The next day, when the chicks arrived we got a crash course in solar radiation, thermo-regulation and the promise of a much less fossil-fuel-intensive manner of brooding chickens.

I quickly found out that the hoop house (with the window, door and roll-up side closed) is capable of reaching internal temperatures in excess of 120°F in the sun.  While chicks need some pretty stifilingly-warm temperatures to be comfortable, 120°F is too darn warm.  Thankfully the roll-up side makes a quick work of ventilating such a space.

160504-IMG_20160504_163737333

The rest of the chick-comfort problem was solved by the addition of some additional shade via an old tarp hung in the big fat middle of everything. The big metal disc under the tarp is our propane brooder that keeps the chicks warm at night.  In it’s former location inside the barn, the propane brooder had to run all day as well. This year, thanks to all the free solar heat in the hoop house, the brooder never kicks on during the day.

All told the hoop house is working out well for a brooder, it just demands a fair bit of vigilance in getting the ventilation setup every morning when the sun comes out.  This already has us kicking around ideas about building a dedicated brooder-house sometime in the future, something with a little more thermal mass and insulation.  The hoop house (and a warm spring) have allowed us to start chicks over a month earlier than last year.  We’re always looking for ways to brood chicks earlier, because that means we can have chicken to sell earlier in the market season.

 

Chicks are here!

4 May

160504-IMG_20160504_172306

We’ve been working hard to get our new brooder house setup because today was the deadline.  Today is chick day.

I’m happy to report that everything went off without a hitch.

160504-IMG_20160504_161649532

The chicks seem pretty happy with their new setup, and we’re happy because it’s one more thing to scratch off the to-do list.

Stay tuned for all the gory details about the hoop house we built for the little critters.

 

The Babes of Spring

19 Apr

Spring is doing it’s thing.

That means that we’re running around trying to get a handle on all the new babies that are popping up everywhere you look.

160415-IMG_20160415_095214894

The sows have started farrowing, which means that there are now plenty of little oinkers running around.

160404-IMG_20160404_172702171

We figured out that not quite all of our big mean barn cats are male.  The cat in question (a very skittish creature named Emer-cat) was found to be female when she was spotted behind the stack of strawbales with her new litter of kittens.  This has, understandably, become a major locus of activity for the preschool crowd.

160413-IMG_20160413_134200305

Speaking of which, there are other babies that are keeping us plenty busy too.

Gotta love springtime on the farm, it’s almost too much cute to handle.

Pastured Poultry Pen v3.0

11 Apr

As our farm continues to grow we find ourselves outgrowing some of the equipment that we started with.  This time it’s the pastured poultry pens.

The old model (v2.1) is still a great bit of equipment if you’ve got lots of time and not a lot of money.  After all, the coroplast election signs are free and the rest of the materials only add up to about $50 per pen.

The downside is that the old pens aren’t the sturdiest things around.  After a two years of wind, snow and the incessant meddling of wayward cattle, the coroplast pens were in need of major refitting if they were to see another year of service.

160312-IMG_20160312_172851772

Witness the exquisite condition of the old pen (on the right) compared to the new v3.0 pen (on the left).

140517-IMG_20140517_171610

We started with the same base as the old v2.1 pen.  A pair of 2″x6″x12’s for the runners and three 2″x4″x8’s to tie it all together. The footprint is 8’x12′ and we’ve been pretty happy with that size.  It’ll house about 50 full grown broilers when moved daily.  If you’re hurting for space you can get 75 birds in a pen, but you’ll have to move it twice a day.

160308-IMG_20160308_175105568

Once you’ve got the base squared away it’s time to dust off that hoop-bender you built.

160310-IMG_20160310_153041700

Get 14 or so sticks of 3/4″ EMT conduit and mark them at 12″

160310-IMG_20160310_153049832

and at 87.25″ then make like Bender Bending Rodríguez and, well, bend them.  The bend should start at the 12″ mark and continue to (or a bit past) the 87.25″ mark.  

160310-IMG_20160310_154644370

After bending, cut the hoops at the 87.25″ mark and you should have something like this.

160310-IMG_20160310_160610103

Now take two of those hoop-halves, connect them with a 3/4″ conduit union and set them arrange them on the base thusly.

160311-IMG_20160311_110533499

Cover the structure with 4 sheets of 12′ steel roofing and fill in the gap with chicken wire.  No need for additional bracing, the EMT and steel roofing provide ample rigidity.

160311-IMG_20160311_142447617

One big change for the v3.0 pen is that there is no chicken wire down at pig, predator & dog height which ought to help keep the chickens a bit safer.  It should also keep them more comfortable as the young broilers benefit from having a solid windbreak, and the older broilers like to have plenty of shade.

160311-IMG_20160311_143939088

Now to fill in those ends.  They get the same treatment, sheet metal on the bottom, chicken wire on the top, but there is the small matter of providing a structure by which to attach said material.

160311-IMG_20160311_135633796

I like 2×2’s for this purpose, really 2×4’s that I’ve ripped in half because that’s cheaper.

And have I mentioned copious bracing?  Bracing is awesome.

160311-IMG_20160311_135648737

While one end is almost frighteningly easy, one end has a door in it, which takes more time than anything else to get put together.

160311-IMG_20160311_143908717

The door is going to be quite a bit bigger on the v3.0 pens, witness the old v2.0 door sitting on the new v3.0 frame.  The center height of the new pens is right about 5’6″ which is a marked improvement over the old pens which required a lot of stooping and crouching to get inside.

160311-IMG_20160311_173437958

Building an odd-shaped door is always lots of fun.  But at least the rigid metal skin on the bottom half makes it a lot easier.

160311-IMG_20160311_175447923

The top half of the door will be chicken wire, so I decided to use a spare bit of 1/2″ EMT conduit to make the top curve of the door.

160311-IMG_20160311_175854937

Braced copiously of course.

160312-IMG_20160312_124309905

And then find a nice spot to mount the door latch.

160312-IMG_20160312_124301532

And the strike.

160312-IMG_20160312_124325473

And suddenly you’ve got a door.  A nice big door.  Good for carrying those big 4′ chicken feeders through.

The best part is that the chickens can no longer see you (the farmer) through the door.  When broiler chickens, which are bred to have voracious appetites, see you coming they quickly pile up against the door that you’re approaching.  The new door should stop all that sillyness and let me get through the door without so many chickens underfoot.

160405-IMG_20160405_102253051

A bigger door also allows us to move the water bucket inside, which means that the cows can no longer continue their campaign of water thefts and waterer sabotage that they’ve been waging against the chickens.  The cows will now have to walk an extra 100 feet to drink from their water tank, the poor dears.

160314-IMG_20160314_173033002

After the first pen was completed it went out in the barnyard for torture testing.  The pigs and cows quickly put it through it’s paces as a scratching post.  It has survived without any damage whatsoever, which is a huge improvement.

The new pens are equal parts more expensive and heavier than the old pens.  The expense is now something like $150-175 per pen.  That’s still eminently reasonable given the huge increase in durability, but if you’re bootstrapping yourself into a new farming venture the v2.1 pen is still a good option at less than $50.  Just be aware that the v2.1 pens are not going to last long, especially in a mixed-livestock situation.

The biggest downside to the new pens is that they’re significantly heavier.  All that extra metal means that it’s no longer feasible to drag these pens around by hand without a little help.  I think one of the Salatin-style dolleys might be in order.

 

 

 

 

 

 

 

 

2016 Crop Plans

25 Mar

rp_25453888886_3aeb00ae8c.jpg

We’ve just wrapped up our crop planning for the year, and here’s what it looks like.

2016-Crop-Map

This year, at least on the crop map, we’re going to look like an awful lot of other farms around here: planting corn & beans.

True to form, we will be doing things a bit differently than most.  Sure, the soybeans we’ll be planting are the same-ol’ same-ol’ variety that we planted last year, but soybeans require processing (roasting specifically) before they can be fed to livestock, so we plan on selling our beans at the local feed mill just like everybody else.

The corn is a different story.

With all of the pigs, chickens and turkeys that we raise, we end up buying a fair amount of corn.  And we know something that many other farmers are just beginning to figure out: there is a lot of demand out there for critters that are fed a non-GMO diet.  I see a lot of farmers online (I’m looking at you r/farming) who can’t seem to accept this new reality.

It seems that they’d rather spend their time complaining that:

A.) consumers don’t know what’s best for themselves

B.) they can’t make any money farming

The solution seems pretty straight forward to me, just grow what people want to buy and you’ll solve both problems (radical, I know).

So this year we’re getting into the non-GMO corn game.  Nobody around here sells non-GMO corn, so this is the only way for us to get some to feed our critters.  We’re putting 12 acres into corn this year, which should yield 1,980 bushels if we get the same yield that we did the last time we grew corn. That’ll put a pretty big dent in our feed bill.

 

A photo posted by Andrew (@greenmachinefarm) on

I was very pleased to find out, upon crunching all the numbers, that the non-GMO corn we’re planting ought to come out a little cheaper than the last corn crop we planted. It’s said that when planting non-GMO crops you save some money on seed, but spend more on chemicals (herbicide & pesticide) making the non-GMO crop more expensive.  That might have been the case for us if we weren’t following a better crop rotation.

2016 corn crop (non-GMO) following soybeans

Seed: $49/acre

Chemicals: $125/acre

Fertilizer: $62.42/acre

Total: $236.93/acre

 

2014 corn crop (GMO) following corn

Seed: $116/acre

Chemicals: $49/acre

Fertilizer: $238/acre

Total: $403/acre

 

Crop rotation saved us a fair bit of money on the fertilizer, beans fix nitrogen into the soil which means the crop that follows beans needs less fertilizer.  But even if the fertilizer was the same the non-GMO corn would only be $9/acre more than GMO corn.  The savings on seed is almost enough to offset the increased spending on chemicals.

So that’s the plan.  It’s only a plan on paper at this point, so we’ll see how it works out as we transition to farming in the dirt later this spring.

Spring Baby

21 Mar

rp_25868605691_28efd424d6.jpg

Springtime on the farm = Babies.

Usually that means piglets, chickens and such, but this week it means that we have a brand new human.

Meet Arlo, he’s 3 days old and fairly adorable (I’ll admit to a slight bias in this regard).

160319-IMG_20160319_115842400

We decided that since we’re getting the hang of raising livestock, we’d give raising humans another shot.  Baby humans take quite a bit more care and feeding, but they’re supposed to be pretty cool.  This particular human came in a bit smaller than his sibling at “only” 9lb 5oz.  His mother is grateful.

And I’ll leave you with a little game I like to call “Father or Son?”

Hoop Bender

10 Mar

rp_25595829571_bf857ba125.jpg

If you’ve spent much time online looking at sustainable ag and/or garden-y type stuff then you’ve probably ventured upon a myriad of uses for bent-up pieces of metal tubing.  Hoops they call them.

Hoops are made into all kinds of fun stuff like row covers, high tunnels, livestock shelters and the like. You can find some commercially-made hoop benders out there, but a hoop bender is pretty simple.  For being so simple, there should be a plethora of how-to’s out there on the internet showing how to make one, right?  Nope.

So here you go: make yourself a hoop bender.

160310-IMG_20160310_130553911

Step 1: Math.

Figure out what size hoop you need.  In my case I wanted a hoop with an 8′ diameter.  You may assume that you can build a hoop bender to a nice 4′ radius and that the resulting hoops will be 8′ diameter.  But you would be wrong.  How do I know?  Well, just trust me, it won’t turn out like that.  It will make a dandy 10′ diameter hoop though.

So if a 48′ radius = a 10′ hoop (48/10=4.8)

To get the correct size for an 8′ hoop, you just take 8*4.8=38.4

38.5″ seems like it ought to be just the ticket for a 8′ hoop.

Now, with all the math out of the way, get a nice sheet of something.  Maybe OSB, it’s cheap and strong.  Oh, and while you’re at it round up some scraps of 2″ scrap lumber.  I used a bunch of 2×6 scraps.

A photo posted by Andrew (@greenmachinefarm) on

Trace out an arc of the proscribed diameter (38.5″ in our case) on a half sheet of OSB, and start laying out your scraps of 2″ lumber to cover up said arc.

Draw another arc of the appropriate size on top of the 2″ lumber and start cutting away the excess.

160308-IMG_20160308_175105568

Place all the little 2″ peices back on the OSB in the right order and get to gluing and screwing them down.  My operating assumption is that glue and screws should be strong enough for bending 1.375″ chain-link top rail.  It does a bang-up job bending 3/4″ EMT conduit.

160310-IMG_20160310_130259527

The last order of business is having something on one end to hold the tube as it’s bent.  I opted to cut a small slot near the end and thread a large hose clamp through.  Good enough, I’ll double it up later if it looks like the top-rail might need more to hold it.

160310-IMG_20160310_130410231

Secure your brand-new hoop bender to the work surface of your choosing (clamps or screws ought to do the trick) and get bending.

Mega-Waterer v2.1

3 Mar

rp_24710845119_17b57204c2.jpg

As much as I wanted to like the new Mega-Waterer 2.0, it was giving me problems.

Despite my best efforts, the freezing continued to be a problem.

The first (and likely most important) step in mitigating this problem was to move the waterer away from the windows and doors.  This makes filling it a bit more of a pain, but it’s not so bad when you’ve got a new fancy filler thingie.  Windows and doors are convenient for filling, but they have a nasty tendency to let a lot of cold air in, especially in a drafty chicken coop.

Then there were the hardware updates:

160210-IMG_20160210_115439612

The body of the waterer assembly all got a nice layer of foam insulation.

160210-IMG_20160210_122729960

Followed by a few layers of duct tape.  As I have found out the hard way, chickens will absolutely destroy any unprotected insulation in approximately 2.4 seconds.  Any visible insulation is history, so apply duct tape liberally.

160210-IMG_20160210_144744917

Inside the reservoir a few reliability improvements were made as well.  The water pump was secured to the hose with an excessive number of zip-ties.  The other end of the hose was secured to it’s fitting with a screw.  Without all the extra fasteners the whole thing tended to disassemble itself at inopportune times.
