My @ 1 and a half year old Ameraucana is unable to walk normally today. She was fine yesterday evening. This morning she is waddling/limping slowly as if something was wrong with her legs. I picked her up and gently stretched out her legs. She did waddle to the feed and eat; she was interested in the mealworms I gave. Now she is just "sitting" as if she were on the nest. ??? Please note: I've only had chickens for 2 months (I inherited them).
