So I have Buff Orpington named Omelet that for the last two days has been sitting on the roost. She came out for a little while yesterday but went back into the henhouse. When I was cleaning the henhouse she pecked my head a couple times and got really big, like a Bloomin Onion chicken. All her feathers were up, her butt was up and her head shrunk down into her body so she looked super round and huge. This morning, same thing...I let all the hens outside and she didn't come out. I went to the henhouse about an hour later to gather eggs...there were three...not hers, but she was still up on the roost all blown out when I approached her. Is there anyone out there that has had a similar situation, and can you help me understand what she is doing, and what I can do to help her get out of her funk?
