Only use dura 10 if bumble is gone systemic I believe, that's when you bring out the big guns. I'd just clean the foot real good paint with the iodine put to bed. This has been going on for quite a while with Pet Ducks duck and the heat and swelling makes it seem like an antibiotic is needed.If using duramycin 10 as haunted 55 suggested is that if bumble is really bad or using with mild bumble ok if so should I put in a waterer just for drinking or can it be used in their bucket they drink and dunk in.
