Okay, I had posted that we thought the Roo was responsible for killing two of our hens(he is now quarantined to a dog crate inside the coop)...well, now this morning I've noticed one of our Buff Oripintons has a cough... any ideas what might be going on, will my buff be the next to die? Is the coughing something that my other two could've had and could've caused their sudden deaths?? I'm freaking out, I don't want anymore of the girls to die!
