I know these questions may seem silly or unnecessary, but I never even heard of a chicken tractor until a couple weeks ago, so I just don't know that much about this. We have almost an acre, and while it would be nice to have the chickens in the tractor in what I call "the back 40", I don't think it's practical because there is no shade whatsoever back there. We could put them in "the dog yard" because it's shaded and cooler and that leads me to this: do people leave their chickens in the tractors overnight or do they move them back into the coop at night? I've seen different designs of tractors that have smaller doors where you can take eggs out, etc, and I'm thinking we would only have ours in this thing during the day. Do they generally live in this thing during the summer? Anyone want to share what they do? Thanks!
