Hi everyone! I am searching for some advice. My polish roo is 1 year old. He has been congested and coughing for a week. No nasal drainage or eye drainage that I notice, just a rattly cough. Ive been giving him antibiotics in his water, but he still is rattling so I just got some Tylan 50 at Tractor Supply. Ive injected him twice today so far with 0.5 cc's. Am I doing the right thing??? He does appear to have lost some weight in the last week. Not sure what else to do for him. I was supposed to show him in the fair, but now cant because I dont want to get anyone else sick or any of my others sick. Thanks!
