Bumblefoot and eggbinding are, by far, the easiest problems to fix! Wish these were the only ones I've had to deal with in my flock, but I started out with hybrids, so was glad I did my research before the problems cropped up.
Make sure to change that bandage and repack with antibiotic cream(without pain killers) very often till it's healing over. I'd stick to changing daily for the first few days, then let it go a day or two then slowly stretch out till it's well healed over. If it's wet and muddy, keep to changing...
OD = more stressful on the kidneys/liver may not be an issue for a one-off, but keep an eye on the urates after - yellow urates would indicate liver/kidney stress - can go all the way up to a tumeric yellow if bad.
I know some painkillers effectiveness wanes with time, so perhaps the side...
Meloxicam will put a strain on their kidneys, I think... That or liver, can't recall... So use it with caution. If the bumblefoot isn't so bad, I personally wouldn't opt for painkillers as they tend to fare well without them anyway and I'd rather not stress their system.
