I have a 4 year old Easter egger hen who has had a limp for about 3 days now. I've looked at her foot and the only thing I see or feel is her joint feels hot. Foot looks fine. She always standing with one leg up. She can put some weight on it to walk but you can tell it must hurt her. What can I do? I don't want her to keep feeling bad. What does the hot joint mean? I'm wondering if she just jumped off of something and twisted her leg.
