Well, the vet desibribed her a as a case with 'severe absesses'. Too do an operation at first she said they would have too go down too the bone. Vet - rap and tripple antibiotic cream is good. I have a cream called Chlorhexidine leave - on lotion which I got from the vet. You could ask your vet if they have any. As well as gauze pad to put on with the lotion. Then rap with vet - rap making sure it is not too tight, but tight enough that it won't come off. You have mentioned that you have a booties for him. I would put them on top of the vet - rap. Re - rap every day if you can, kepping it clean. As well as an epson salt soak for at least 10 minutes and a 1% betadine souloution towl soak for at least another 20 minutes. For the surgery I would recomend tweezers and cotton wool to mop up any bood that comes out, just in case. Hope your duck gets better soon. I have nearly eradicated bumble foot from my flock since seeing it now about 6 months ago (a late christmas present seemingly), so feel your pain.
