Good evening. I had three Dark Brahma chickens. Two hens and a rooster. Last weekend they started with sneezing and runny eyes. I lost one of the hens on Sunday. I started Albon in their water everyday, and gave them three days worth of Tylan injections. They were better and the remaining hen started laying eggs again on wednesday, and is still laying, but the rooster is starting to make sounds when he breaths again and I heard him sneeze again. I am still giving them the Albon, but should I give them more Tylan or try something else? Any help would be great!!!
