Keep soaking and wrapping every day too. See if you can squeeze it out.
The drug is very tough on their stomach. I gave our ducks yogurt but I'm not sure if that really helped. Just make sure there is plenty of water available. Expect projectile diarrhea.
Good luck and keep us updated!

Found this. Gives how to give shot and dosage. I would double check the drug you have because mine actually said pen g on it, not bactacillan
I can't see the whole label but it looks like Pen G Procaine. That's what we used. I used another thread to figure out the dose. I gave our ducks an injection in their breast with a 22 gauge. The solution is really thick, though, so you will needed an 18 to draw.
I'll search for the forum I used
Congratulations on your work so far!
Now for the bumblefoot. Most definitely a bad case. If the leg is already got, you might consider antibiotics. It can go from bad to worse overnight.
1. Soak at least 20 minutes three times a day in Epsom salt water.
2. Here there are a lot of choices...
probably he is in shock still. Keep him warm. The wounds are not nearly as bad as i thought they would be he is just missing feathers i don't see any wounds that are deeper then the skin. How long has he not eaten?
