I had a hen go broody when I took her out of the flock. She was being mean to all the other hens and I wanted to change her status to see if she would be a little nicer. So I put her in a large dog crate for a week and let her do her own thing by herself. I noticed she was sitting on an egg and every time I saw her she was sitting on that egg (she is an old chicken that lays very little these days). When I removed the egg it had clearly been incubated, then I noticed the hen had pecked all her under belly feathers out, I put her back with the group and she is a little nicer, but she has not laid an egg since (not really worried cause she is so old) but I think she was all set to be a mama. It made me wonder if I put a hen in a cage like that again, if that works to get them in a broody mood? idk just wanted to share my thoughts there
