@TroyerGal , I'm treating a Pekin drake with a bumble now. I've tried to be as non-invasive as possible to allow his own body to heal itself as much as possible, just spraying the spot with Vetericyn for a couple of weeks. It seemed to be getting better, albeit very slowly. Today warmed up enough to allow him a bath outside (he's inside on pine shavings) and he spent about 30 mins in the water. Lifting him right out of his bath, I was able to pull the softened scab off with tweezers. Despite the scab, I didn't see an infection "seed", but I did squeeze it to be sure. There was almost no bleeding, too. After packing the area with triple antibiotic ointment and gauze, followed by elastic bandaging, I put him back in the brooder. I think he's well on his way to recovery and will be back out with his Runner GF and kids soon.
