thank you for the information. I think I will do bloodwork on two of the ones with symptoms. This really sucks as I am the only person providing some of these breeds in my city. The ones with symptooms right now is the roo and some pullets, the laying hens are not showing any symptoms just yet...
My chickens have been constantly sneezing, I am not sure if it is a respiratory infection or because I just changed to coco chips for their run. They have been sneezing for over a week now, the issue is that I just introduced a new rooster to my flock which might have given a virus to everyone...
