Yes, it could work with poultry if you are able to flush deep enough into the would. With the duck, she had one tear and a coupleof puncture wounds. I stitched the tear.
Honestly, I don't think I was able to flush deep enough into the puncture wound - and it was the first puncture wound I had dealt with. I later had a sort of abscess/puncture wound that was slightly bigger that I could sort of stuff with thin strips of gauze ( soaked in betadine and then coated with honey. Flushed & repacked daily) That worked quite well! But the tiny (diameter) wound on the duck - plus the thick abundance of feathers making ot more difficult - just wasn't possible.. If something like that happens again, I would probably cut/pluck feathers surrounding the wound, and possibly even cut the wound itself open a bit for better flushing..though I hate cutting them - so not sure I could do that WELL...especially given my assistant (hubby is not really the best at holding them

- but he tries!)
They are all so nerve-wracking!

I just do the best I can, and, hopefully, learn more each time. Do wish there was access to an avian vet - if for nothing else but suggestions and possibly anti-biotics!!

You know,
@BY Bob - you said you like teaching. Maybe you (?with help of vet or something?) could develop the equivalent of EMT training - but for chickens and backyard pets. I would certainly pay to take that - especially if you were teaching it!!!
