My chickens and goats share a yard and shed, which is a nice arrangement, because the goats keep predators away from the chickens. I thought I'd share the feeder I came up with for feeding the chickens without letting the goats get into the chicken feed. As a bonus, there's no food waste, because the chickens can't scratch the food out of it. It's been in operation for 3 months now, and is working great!

It's basically just a tall box with a baffle inside and a floor slanted toward the front, just like all the other feeders with similar shapes. The difference is that instead of a front opening, I drilled holes with a 2" hole saw for the chickens to stick their heads through to eat. The top has hinges and a latch, to keep inquisitive goats from getting in that way, and it easily holds a 25-lb bag of feed.
