Ok so I know a little about layers but not much about meat birds. That being said... I see a lot of folks on here that use tractors for their meat birds. But in them I see no roosts. What do they do just sleep on the ground. And what about square feet per bird? Looking at getting like two dozen or so, what size tractor do I need. I tried to look this stuff up so I didn't have to make a new post but I couldn't find what I was looking for. Please lead me in the right direction... thanks.
