Dan, Bacterial infections are hard to get rid of in a grey. Talon came to us with one, and it took a year and a half to clear her of it. Our vet said not to kiss them on the beak, share utensils, or glasses with them.
Well, that lasted like for one day...........Too many people in this house to obey the rules. But I admit, I couldn't stop the kissing on the beak thing, no way, no how, uh-uh!! :pinch:
