I have 2 ducks, both with issues from bumblefoot. Affected legs are hot in comparison to the other leg and affected legs are swollen and tenderwith limited to no movement. I've been doing the following: epsom salts soaks twice a day, Neosporin, veterycin spray, gauze and wrapping with vet wrap. I can't see that anything is improving. I've called all our local vets, and neither sees ducks. I feel like they need antibiotics, but where can I get? What do I get? And how to administer??? Please help! I do not want to lose these girls!
