I posted a few days ago. I've had my 4 8month old Delawares for exactly a week today. 1 came down with a cold the next day, and has kept getting worse. 2 others also seemed be coming down with it. Mostly wheezing, some coughing and sneezing. So yesterday, the first one seemed to be a little better, but I started them on antibiotics (Tylan 50, but I did it orally.) anyway. I was glad b/c last night, the first hen who had gotten sick was wheezing so badly I was afraid she was going to be dead this morning. I just caught them all and dosed them again and they are all 100% better. No coughing or wheezing whatsoever. So should I assume this was bacterial and it's gone once we finish the round of abx, or do you think I should still pursue having them tested for the various viruses that cause crd? The guy we got them from will be at the market again today, so sould we drive down there to talk to him? Thanks for any thoughts!
