I accidentally stepped back on to my daughters Indian Runner duck . His wing was under my foot , when he got up he shook himself and flapped his wings , which were fine , but he's now limping ! I checked all down the joint and underneath his foot and everything seems ok , but he's still limping . I feel absolutely awful as I was locking them in their pen for my Daughter and was just reaching to add extra straw in their bed when he got right under my feet . He was getting stressed as I was checking him over so I've just left him in his pen with his mate to be quiet ! Is that the best course of action ?
