I noticed a week or so ago that my Lavender Orpington hen was walking with a limp. Then this past week she wouldn't even come out of the coop or even down of the roost. So we got her out of coop and sat her on ground and she wouldn't even try to walk like she couldn't. So we picked her up and looked at her legs and one looked like it was pulled out of the socket, it was sort of just hanging there. I gave her a bath in warm water and put her in a cage with food and water so she can rest by herself. Will this heal on its own? Has anyone else ever had this happen to chicken?
