I just spoke with Diane at Durvet, Inc - She informed me that for 800mg dose, mix one gallon of water with 3 teaspoons of the medicine.
I have a peacock that looks like a chipmunk, he is very swollen, I am going to start with an 800mg dose and if it gets better soon, I will go to a 400mg dose.
I called our local vet regarding his eye and was told there was nothing "over the counter", however, because of the internet, I discovered there are many over the counter remedies including an injectable medicine, Tylan 50. The vet said we could bring the peacock in and she could try to asses the issue, but the capture of a full grown peacock is not something I want to consider at this time.
I am going to administer the Duamycin-10 first.
I really hope this works!
