Swelling on Foot

[Lilquacks21]

I have posted here regarding bumblefoot and have treated it in the past, but now I have noticed swelling on my ducks foot. She was favoring the foot and it feels warm, but there was no black “scab” or cuts like typical bumblefoot. I have been giving her warm water soaks with chlorohexidine, applying triple antibiotic ointment and prid (just in case) and wrapping the foot. It’s been about a week, and I noticed that now the black skin on her foot is peeling away??
