I've never seen bumblefoot as a long scab along the foot like that (not that I'm an expert and have seen lots of cases, but I've looked at a lot of posts on BYC). @Isaac 0 - do you think this is definitely bumble? Didn't you say that when you rescued her she had been stuck in the water and unable to get out? This makes me wonder if her foot shouldn't be bandaged constantly, unless there's an open wound of course. I don't know for sure, but my vet did tell me that a wet bandage is worse than no bandage at all. So maybe applying the iodine or meds and putting a bandage on at night when she will keep it dry is a good start - unless of course you've peeled back scab and raw skin might get infected. I've never dealt with the edge of the foot, but one thing I find works well in bandaging is to wrap the vet wrap around the foot and a wrap around the ankle, then come loosely over one side of the web in between two toes. I keep this loose so the webbing doesn't pull back when the duck walks. After you come between the toes, just continue to wrap around the foot and ankle to secure it. I just try to make sure my duck's foot is pretty flat so she can walk normally. If you want to see a picture I can post one tomorrow when I do my duck's foot, so you can see what I mean. Maybe you've already solved the issue!
