One of our 1-year old Plymouth barred Rock hens has gone broody, and we just received 12 fertile hatching eggs we plan on sticking under her. I've been reading about "Broody Boxes" to keep her contained/isolated, and was wondering if anyone has ever used a large plastic dog kennel like as a broody box. Obviously, we would create a nest in the back, line the floor with straw, and provide food and water bowls, which should provide a decent amount of space for her. Can anyone think of a reason this wouldn't work? Would closing the door unless we were out there watching be a good or bad idea?
