The ferocious livestock guard dog puppies got a new dog feeder, one that holds a whole 50# bag of the large-breed puppy food.
That lasted a whole 3-4 days until the piglets found it. Then I raised up the feeder on some bricks to be a bit more exclusionary for said piglets. “Surely” I said, “this has to be good enough to keep piglets out and let puppies in.”
No dice.
Then I changed up the fence to be a bit more exclusionary for said piglets. “Surely” I said, “there has to be a way to keep piglets out and let puppies in.”
Don’t underestimate pigs, especially when tempted with food that is more expensive than their regular fare.
