Yes she did and she also didn't try to do this every 2 days. Did you get the decolorized iodine? Look, more isn't better with this, I'm sorry, but it just isn't. If you had to have stitches from a med. Doctor, do they tell you to clean and change the bandage every couple of days? No they don't, they want the body to heal and constant fiddling with things isn't going to do it. As soon as you put the iodine on, it is being drawn in and killing infection and the body, if allowed, will push this to the skin surface.
If me, I would pull the scab after soaking, just as Amiga said. I use an X-Acto knife blade to lift a corner and then use tweezers to pull it off. Everything sterilized! I then check inside the wound and pull out any pus I can readily get to. You can try gently squeezing and I would also look/feel really well to see if there is something still in there. After this I would again soak the foot in warm water or in my case put the duck back into the tub so it can swim around for a half hour or so. Then I would take it out, dry the foot and put the colorless iodine on, dry it and put her back in a crate or with the rest of the flock.
You cannot speed this up unless you want to get into actual cutting of the skin and digging into the wound. The only other option beyond the cutting, would be a Vet and having them do it for you.
