I agree completely!
Even just the warm epsomsalts or saline is good for helping her recover. Daily soaking, or as often as you can manage it, will help. Anything you can do to keep her foot clean and dry too. (Easier said than done, I know!) The neosporin option will collect dirt and debris much easier than the betadine. Soak, dry, betadine dip, air dry, then onto the substrate. If there’s any way to get her onto coarser bedding it would be good.
Can chickens bruise under their scales? I know they can bruise on their muscles and it changes the texture and quality of the meat. Just the colouration seems to be changing, and the dark spots really remind me of bruising...
I’m just coming off a very bad sprain on my ankle, so I’m probably just projecting... but I managed to bruise in places I couldn’t see, and all the way down to the base of my toes, it took me over a week for the swelling to go down enough for my shoe to fit on. Just from a rolled ankle... I really do feel for your girl, foot and ankle pain is awful!
