My chicken miss Vana White is acting funky. She is a little over a year now and a mixed breed gal. She just recently molted and is now almost acting like she had a stroke or some kind of head truama (walking around really slow and not as fearful of me) she is all fluffed up and her comb is a dark brown redish color. She is sleeping in the nesting boxes and is not as fast as she used to be. I caught her for the first time in over a year and she does have a single egg in there but her tail is raised and she even shakes it from time to time. I have no idea what is going on but she's eatting great and still struts around during the day. I don't have a clue whats up with her. Please help!
