Thanks for the responses. One of my duck groups said the photos look more like bad callouses rather than bumblefoot. I think I agree since this morning the open one doesn't seem to have any sign of infection. It's definitely healthy tissue. I'm not gonna mess with the right foot. So I soaked his feet real good, applied spray and neo on a gauze pad and wrapped it up. Moved him out into the garage where the rest of the flock came to visit for a bit this morning, and now he's just chilling. I'm hoping he can go back out by early next week. Ours strictly free range, and if he can't walk or run he's literally a sitting duck out on our property for fox, coyote, bobcat, loose dogs, etc... so he's gotta be a house duck until then.
