I putdown one of my Ameraucana’s yesterday she had been suffering from what I believe is either CRD or pneumonia. Her eyes were bubbly and face swollen with a heavy wheezing or breathing. We had her isolated or quarantined from the others and started giving her Duramycin-10 for about a week without any good result. The Duramycin-10 was suggested by our local Farm Supply store. Last night we noticed that our Silver Wyandotte was exhibiting the same early symptoms. I did give her some of the Duramycin-10 but decided to get some Tylan 50 and gave her, her first injection this afternoon. Everyone here seems to lean towards the Tylan for respiratory problems so I’m trying it. I have quarantined her and cleaned the coop and sprayed down with a mild bleach solution. I’m hoping this will not become an epidemic that will take out all of the birds. Any other Ideas as to what I can do?
