Do you guys have trouble with your chickens wanting to escape when you open the hatch to the nest boxes? I'm going to have three nest boxes, and I had been planning to have the back be one long board that is hinged and swings down, so it would all be open from the back for egg collecting. But now that I'm thinking about it, I wonder if the chickens will fly out of one nest while I'm getting eggs out of a different one. So maybe I should have three separate doors? Or will they generally choose to be out in the run during the day unless they're laying? I know next to nothing about chickens! Right now they're still in the brooder, but several of them have attempted to escape while the lid is cracked open to refresh their food or water.
