Help! Duck health emergency question

This site has some good info on treating lice and mites:
https://the-chicken-chick.com/poultry-lice-and-mites-identification/
but it does not list a method for Canadians to treat them.

Thanks so much for all of the info everyone, we soaked, cleaned and wrapped her foot. Removed the pool and minimized their pen and put landscape fabric down to cover the gravel and put straw on top with fresh water and food. Will do our best to treat for bugs if that’s the issue and keep treating the foot.
I tried to get a better pic but not sure it’s much better, it’s a pretty big lump and soaking didn’t seem to do much, i tried pressing it to see if there was puss and didn’t seem to have any come out but not sure if you’d have to cut the skin a bit to check for that. I do have first aid skills and read about dealing with advanced cases just not sure how to tell if it’s gone that far although feeling like it might have. Her beak is pale and her feathers are scruffy.
Will monitor her but not sure what else we would be able to do other than drain the foot if that’s what needs to happen

What’s the thoughts on putting oyster shells out? After DJ died yesterday someone said lay off the oyster shells, but if she had been egg bound wouldn’t it have been the opposite issue? Is there any harm in having the shells for them? The male seems to eat them too which I know he maybe shouldn’t

I see no harm in offering free choice oyster shell on the side.

So a few days have passed, she is still alive thankfully, and looking a bit better maybe, but limping hard and holding her foot up a lot. Her beak is still pale. I’ve been soaking in epsom and cleaning and bandaging best I can, feel like I may have to try and do the surgery I keep reading about as it’s a big lump and not sure soaking will be enough.
Was also thinking of giving electrolytes as I’ve read that can help- the homemade one with molasses and baking soda.
