@Peas4Ducks are you seeing any improvement with the duck? If you need to wrap her foot, I'm happy to show you what I use like
@Miss Lydia mentioned above.
Did the vet xray the ducks leg and foot? The lack of a wound with swelling in the ankle sounds eerily familiar. Bumblefoot is the most common, especially with heavyweights like Pekins, but the more I read, the more I feel like I was wrong on my ducks initial diagnosis back then. She DID in fact develop bumblefoot. I'm not 100% sure about a difference in treatment between another diagnosis. I did have to remove pus (hard chunks) from her ankle by making incisions on multiple occasions. Since you've got an Avian vet, I'm confident they know way more than I do, but I just worry since the vet wasn't enthusiastic about her recovery. I wonder if the vet suspected something more than severe/Grade 5 bumblefoot? I hope she's improving
