So sorry, I don't see bumble on her foot. What have you done besides the penicillin?
How long has she been like this? Pictures of the whole duck or a video would even be better. Have you treated for botulism? Are you using the liquid B Complex?
Any types of feed that may lure him up?
Something I have heard people doing is having friends over and someone gets into a kayak and herds the duck to shore to where friends have made a tunnel so the duck has to walk or run between the people to a crate awaiting him. It may mean someone has to...
Def don't let her back to the pond. She needs to have a good chance of recovery. Sounds great what all you have done!!
Check out Crazy K in texas for duck shoes that is where I got them.

Okay so do both feet. And you can also buy duck shoes But making them for the time being just to get her started would be best. Lots of warm water swim therapy of course you'll have to take her shoes off for that. Give her every chance. I've seen some really good outcomes using the Liquid b complex.
Is this both legs or just the one? Can she stand and walk at all? when did this start?
It looks pretty bad but let's not give up hope until you've tried the liquid b complex. I'd also make her a shoe if she isn't laying her foot flat. You can take a piece of plastic from a cool whip container...
