I am 13, and i have been worrying since I was 10 that my chickens will die of breathing problems. They are the center of my heart, and I do not wish to see them die, because once a terrible Mountain Lion killed Chocolate, a Golden Laced Wyandotte, and killed Rice-Rice, a Silver Laced Wyandotte. Even though it has been three years, I really want to know how chickens could get a Respitory sickness, they are VERY,VERY, serious. Thanks! :!: :idea: :!: :winky: I love <3 :heartbeat: my chickens!!
