Two days ago one of my girls started limping badly. I've kept them all in the coop/run for two days despite all of their protests but decided to let them free range tonight. She crouches down most of the time, but when she walks she's walking almost up on her toes(? for lack of better description?) and on her elbow. I can not feel or see anything abnormal with her. It almost seems like a nerve issue. Anyone have any advice? She's seems to be eating normally and is still getting up in the coop at night. I just feel bad for her because she must be in pain and she continuously does this little cluck while being pet.
