Okay, so we have 20 chickens and our chicken coop is like, a half of a building kinda. And we have a fence around it that's about 200 feet. But, our chickens ate ALL of the grass, and there is nothing left whatsoever, so they eat tons of food. We take them out of their fence sometimes, but we have to watch them constantly because of the neighbors... My dad is thinking about expanding it a little, but is there anything else we can do? Thanks a lot!
