I got this girl today and found this on the bottom of both feet. They do not seem to hurt her. The foot seems to be a little swollen with a black 'scab'. We pulled off one of the 'scabs' to find a large open 'crater' with fresh pink skin inside. If this is in fact bumblefoot, what should I do from here? I would imagine keep clean but what else? How long does it take to heal up? Is anyone else at risk?
