Thanks Amiga!
TonaLee, that sounds so frustrating. I'm sorry you haven't been able to get rid of the bumblefoot yet. Hopefully someone will have some suggestions.
Where and on what is she being housed? Sometimes when ducks have bumblefoot they need to be brought indoors and kept on towels...
I've always used 1 gallon of water when mixing up epsom salt for bumblefoot soaking, but I need a smaller amount right now and I'm not sure what the dosage is? 1 teaspoon of epsom salt for 1 cup of water? That's what I go by for a regular saline solution for putting on cuts etc...
