My two pekin ducks have bumblefoot. One worse than the other (of course the less friendly one). I think it's because they have access to a concrete rock patio and they are in a wire cage at night. I don't really know anything about it except what it looks like and it looks typical. There is a large swelling on the bottom of each foot on the pad and it's black on top of the swelling. I had been noticing the swellings from when they were standing but I guess I was hoping if I didn't look nothing would be there and it would go away. I was picking them up today and noticed "Puddles" had blood on her foot (now all over my white shirt) and turned her on her back to check her feet. Sure enouh classic black spot. I sprayed it with hydrogen peroxide and put them up for the night. So what should I do? Is there any way it will go away on it's own? They don't limp or act like they don't want to walk or anything. I hope I can get this under control fast because I am leaving Friday and my family has to care for the girls. Thanks
