Once I had success with a couple ducks who just had very tiny bumbles - not the big black scabs, or any swelling, and I just used a toothbrush with iodine and gave each bumble area a scrub a couple times a day, then kept them out of water for ten minutes. The bumbles healed up, but they were very small ones.I've got 3 ducks with bumble right now and I was trying to treat them topically but it looks like I'm going to have to start another soak/treat/wrap routine myself. Can you talk more about tricide dips and how you went about that? I'm open to trying some new techniques if you found something that seems to have worked well. How much do you make/how long do you soak etc?
