I currently have my nine chickens in a coop that is large enough for 30 or so chickens, but it's stationary! I started out my chicken journey wanting to have them in a tractor, but I realized I wanted more chickens than that tractor could hold. It seems to me if I want pastured chickens (which I do), that I have gotta go with a paddock system. I think I have everything figured out with the paddock making (I am going to have to put bird netting over it to make sure hawks can't get the chickens during the day), but now I need a coop idea! I am wanting my chickens to be rotated around an orchard, which is both on a slope and irregular in tree placement. I want a coop that is big enough for about 20 chickens but that is ok on a slope and not huge in terms of floor space. Ideally, the chickens won't be in the coop much except to sleep, lay, and eat a bit (mostly they would be eating bugs and stuff, though!). It does not need to be insulated or anything like that, since I have mild winters (san diego, ca). Oh, and I would like something semi-light, at least easy to move! Ideas?!
