Ok so I am soooooooooooo mad right now! I have lost 7 chickens in 3 days. All ROOSTERS. whatever it is, it's only getting my roosters! I have lost a total of 15 in the past 2 months. They start getting lazy (so to speak)... Don't eat, won't drink, start sneezing, coughing, and a lot of saliva comes out of their mouths. No bloody poop, no diarrhea, it just hits em and they die within a day or two. One of my rooster died this morning, a healthy cochin splash rooster. Now my polish rooster is dying from the same thing only he has blood coming out of his mouth!!!! I have tried Tylan and it is NOT helping. I don't know what to do! I have cleaned the coop every other day for the past couple months. Sprayed it down with a bleach/water mix to kill whatever it is! I have sprayed the entire one and a quarter acre they free roam on down with bleach and water also! I'm so upset! I don't know what to do!!! Any advise?!
