Thank you, I have ordered vitamins. Her toes might be slightly turned under compared to the other chickens. She is definitely walking with her feet turned in.
Yes, that is it! I wasn't sure how to describe it, but she is sitting on her hocks. She might be sitting a little bit more than normal, but not much. The chicken at the top of the pecking order has definitely noticed her strange behavior. Thank you so much for responding!
Our chicken has been sitting strangely for the last five or six days. She walks normally and is eating and drinking. She has not laid eggs since this fall. Thank you all for your help.
