I just got these ducks today and all have bumble foot, I got Epsom salt, vetrysin, gauze, and vet wrap, but how much salt to water ratio do I need? and for how long do leave them in it? I will be treating wth the vetrysin 3 times a day, should I soak their feet everyday too? or just initially to get all the dirt and grime off? Thanks!! Also on my oen duck the leg band started to eat her leg, wht can I do for it?? looks a lot worse I relief like she has no musle.
