I think this is bumblefoot? It's weird because she was limping a couple weeks ago but got better in a few days. Now she has this. My husband got some pus out of it yesterday but she is still badly limping today. Ive read on this forum to use tricide neo dip but I can only find it online. Is that the only place to get it without taking my duck to the vet? Is there something else I should be using, like iodine? Soaking is going to be a challenge, as she hates being handled What is the consensus on the most effective treatment?
