Hello I have a 2 year old Muscovy duck called Dot. On her small toe, on the back of her ankle seems to be injured. On her toes there is a yellow pussy look ball but but it also looks like an open wound. I have attached a photo of both the toes. I have read other posts about the same sort of thing but I am just wondering if that is the best thing to do. She seems to be eating and drinking fine. This has happened a while ago but it had seemed to hell over by its self. The main problem is the she keeps on pecking it. Is there anything I can do to help?
