I discovered this just a few days ago when just doing routine foot check - it's on the fleshy part right under the middle toe-nail. It actually looks a little larger to me in the photo than in person, but nonetheless it has a little brown scab and a swelling compared to the other foot. I've been soaking and applying iodine for three days now but I'm unsure of how to proceed, mostly because it's in a spot that is so difficult to see and I don't know how I would wrap it if I pulled the scabby part off. It doesn't seem to affect the duck, but obviously I don't want it to get worse. Has anyone experienced before and is there any advice?

. I'll try wrapping it first and if that doesn't work I'll order the closed toed.
