I have a brown leghorn who I just noticed this morning is walking with a severe limp. She kind of just hops around without putting any weight on one of her feet. I already checked for bumble foot, and it doesn't look like that. She does often try to jump up in the trees in the chicken yard, and get up on the run fence. I suspect she sprained/twisted it jumping or falling. Is there anything I can do for her? or do I just have to let it heal? Thank you!
