Hey everyone. I found this thread hoping it was related to my problem. It kind of is and isn't. As of now I have three chickens that are sick, one rooster and two pullets. It started with my Welsummer pullet. She has stuff coming out of her nostrils like mucus as well as bubbles. Now my silver laced Wyandotte also has those symptoms. About two weeks ago my rooster started crowing different. It was getting shorter each day and more hoarse and raspy. Now he doesn't crow at all and can barely stand. If he stands or walks for more then 2-3 minutes he'll drop down where he is standing. Yesterday I went up into the coop to get my rooster because now he even come down. When I was up there I noticed under the roost bar there is green poop. It is on both sides basically where all the chickens sleep. Do you guys have any idea what might be causing this? I'll try to post pictures as soon as I can.
