Hi
@JennaMadrid, where I live the vet is usually not an option. Had a case of bumble feet with one of my ladies this summer (my duck probably hurt her feet while munching on raspberries)
I first soaked her foot but that didn't work quite well enough and the bumble feet got worse to the point it almost came through her feet on the top.
Than I took
@Miss Lydia 's scalpel approach. Since I had no antibiotics to use, I cleaned the affected foot very well with loads of medical alcohol. and after I got everything out, I applied a thick layer of Betadine (Iodine cream) and taped her foot with some gause and waterproof tape so she could swim.
Had to redo this once the next day and the second day the foot was already almost healed an certainly closed. She recovered without any problems.
If you are going to try this, please be really carefull with the scalpel. And I advise you to find yourself an assistent because being careful, keeping a duck still and removing the pus at once is very tricky...
I don't know how familiar you are with pus in waterfowl. Maybe you already know this, but instead of a liquid kind of material, pus in waterfowls is stringy and solid.
