My husband went it feed the ducks last night and noticed one had a bad injury to her bill. It looks like it was smashed Se has a large cut across the top of her bill with an open wound. It is below her nostrils. She still seams to eat. We poured hydrogen peroxide on it then put a cream we use in our dogs..horsemans dream veterinary cream with aloe over it. We did the same again tonight..ifninhad to guess I'd say the top bill is broken. Ay suggestions on how best to treat her?
