Hey guys. I have a Pekin Duck that’s 5 weeks old he hasn’t been able to walk very well and we figured it was a niacin deficiency so we started adding niacin to his diet. Just today I was getting him out to let him go for a swim and noticed 2 black dots on the top of his foot. I’ve looked it up and Bumblefoot was what I was finding, however, Bumblefoot seems to be on the outside of the foot. Kinda like a scab that can be scraped off. The spots on my duck’s foot are not on top of the skin but I’m the skin. My finger will slide right over it as if they weren’t even there. Could you please tell me what this is and how to treat it. I’m worried. He doesn’t walk much but he’ll stand up and just start quaking like crazy then eventually sit back down, and after a couple of minutes he does it again. I have attached a picture of my duck’s foot.
