I would probably poultice her for a few days to see if it will draw anything before despatching her.
Many people say that bumblefoot has a hard core, more like a corn than puss, so perhaps your expectation of what you would find, or achieve with surgery, was amiss. I'm sure I've seen at least one good video of bumblefoot surgery here on BYC. Unless she is bleeding very badly, I don't think the blood is a problem. I usually consider bleeding at the site of a wound to be a reasonably healthy thing, as long as it isn't excessive. Of course I'm more used to treating horses with injuries and obviously they have a lot more blood to spare than a chicken.
I would use animal lintex to poultice it because I have it my horse's first aid kit but you may find a good recipe for a "bread poultice" online (which is what my parents would have used in their day.)
Either way, good luck. I know I find it particularly difficult to despatch hens and even more so when they are sick, so you have my sympathy.
