Well, that should be a better case scenario than Marek's. But those lines that are susceptible to bumblefoot sure can make a song and dance out of it lol! OK, that's a shoddy way to describe a susceptibility. What I mean is that what could be a simple issue instead can infect the bones and other systems and kill the animal, whereas it doesn't affect non susceptible animals.
I have some lines susceptible to bumblefoot, at first I was merrily eliminating them alongside all other weak lines, with great success... Then I realized I'm eliminating opportunities to learn how to help this issue. And, what happens in future if an animal that happens to be susceptible becomes a treasured pet or has rare and valuable genetics? So, I kept one line. This particular line is currently only represented by a single hen. All five female ancestors of hers that I've owned were all highly susceptible to bumblefoot. I've only actually seen it in some hens, never males, wonder if it's another thing that favors females?
Normally, garlic in the diet regularly knocks bumblefoot out, slowly but surely, and keeps it controlled; but this hen, when in agistment/boarded with the others, went from having normal looking feet to having two grossly swollen balls with toes sticking out of them, due to having no garlic in the diet for many months.
I was going to operate on her; watching her hobble around was painful. Of course, not as painful as it must have been for her. But given their state of health when I got them back I decided to build up their condition before stressing them out with things like surgeries. Building up their condition involved regular garlic... Pretty rapidly one foot completely lost its swelling and went back to normal, and the other is almost all the way back too. No surgery for her, it looks like.
Natural treatments are worth a try in this scenario too, I believe, though some people reckon surgery is the go; but not everybody finds a kernel to remove and surgery can introduce the infection into other areas, so I reckon it's worth avoiding where possible, when there are alternatives.
Best wishes.
