Ducks beak peeling and bleeding

Is he hydrated enough ?

Maybe put more calcium and vitamins in his diet, the vitamins that strengthen his feathers will also help his beak

 

If you can get Poultry Nutri drench is the best stuff around I think. covers alot. Could he have injured his bill? you could also try putting some antibiotic ointment on it but you'd have to do it at night so he didn't wash it off. triple antibiotic or neosporin are good ones, nothing with pain relief in it. Some ACV in their drinking water has healing properties in it 1-2 Tabs to 1 gal of water. don't do the ACV if your using vitamins though. or do it on days you don't do the vitamins. my gander had cut his bill somehow and I used just the ACV in his drinking water healed up pretty fast. Your duck may have a vitamin diff though and need the vitamins more.

That does look like an injury- I would go with Miss Lydia's suggestions - some vitamins, and some topical antibiotics. Even oral antibiotics may be needed at this point. A vet is a good idea, and at the same time I understand it doesn't always work out that we can get a vet's help.

 

Forgot to say TSC carries Nutri Drench and other poultry vitamins too.
