Bumblefoot Question

[FlyAnywayAJ]

I have a chicken with a very swollen foot and she has Bumblefoot. I have done Bumblefoot surgery in the past (not on this particular bird) and am comfortable doing it for this bird. My question is specific to this chicken; as I said her foot is very swollen with a definite limp, but the black scab on the underside of her foot is relatively tiny. It is making me wonder if the size of the scab is comparable to how bad the infection is. Worded another way, since her foot is so swollen and the scab is so small is it likely that there is something else wrong with her foot? Or can the scab be small and the infection still significant?
Anyone have any experience that could help answer my question? Thanks!

Pictures? Could there have been an injury or sprain to the foot?

I should have taken pictures before I did the Bumblefoot removal, it’s all wrapped up now. Sorry!
Definitely wondering if there’s also an injury because the one toe doesn’t seem to move which I thought was potentially odd for “just Bumblefoot”.
