I have a 1 year old female BB White (pet) that has a sinus infection. It is not swollen but has greenish mucus in the nostrils and her eye is getting bubbles as she has trouble breathing through the nostrils. I have been giving injections of Tylan 50 3cc (as I think she is around 35 lbs) 2 x a day for 3 days now. Using Vet Rx to clean the nostrils and 1 drop in the mouth.She has heat in her coop. No other birds affected. How can I clean her sinuses?????? What else can I do?????
