I have a female quail that has been limping for a few days. Upon inspection she has a lump on her leg. She eats,drink, mates, and it laying eggs daily. What could this be? I understand this isn't where quail postings go but I never get much response or help when I do post on the quail thread. I thought maybe this is something someone has dealt with on a chicken or something and can help. I've included a picture. Excuse her poopy feet she ran right into it as I caught her.
