I have a 4x8 chicken tractor attached to a 14x14 run. The coop door is opened in the morning so the chickens can be in the run. About noon, the chickens are let out to free range. I have 5 hens and 1 roo. I would love to let a hen hatch eggs, but I'm afraid that I don't have the place to do that. Surely I can't keep them all in the tractor at night! Wouldn't I have to separate them?
