I have a 19 week old EE whose comb is bright red and she is doing the laying noise. She either stays in the coop on the roost or uses the roost in the pen, but she will not stay on the ground. If I open the door to the nesting box she will get in the box and acts as if she wants me to let her come with me. What is this all about? She was being picked on by roosters who I rehomed last week, but her weird behavior is continuing. It is as if she does not want to be around the other chickens or on the ground. She has always been the first to come out of the coop every morning, now she just stays on the roost. I took her out yesterday about an hour before dusk and she happily walked around the yard eating grass and chasing bugs. HELP, I can't figure this one out. Is it hormonal or what. She is quickly becoming an introvert. Any ideas?
