i noticed one of my ducks limping today. Picked her up and it looked like she had a piece of poo stuck on the bottom of her pad. i went to pick it off but it started bleeding. Looks like she has a thick sore on her foot. It probably didn't get like that overnight, but i am outside about a hundred times a day every day, and no limping before today. i cleaned it up, put Blu-kote on it, and gave her a dose of metacam for the pain. i've never seen bumblefoot. Is that what this is? Any other ideas? Suggestions on treatment?
