My blue Cochin, Petunia, has been broody for about 2 weeks and I plan to give her some chicks in a few days. She has been brooding in a nesting box in the coop. The coop is about 3 feet off the ground. I can put a lot of straw on the ground, so would that help their descent? Do you think they could get back in the coop at night? Or should I move her to a shed? I really want her to raise these chicks for me. I appreciate your experience and help!
