I am new to this site but am in desperate need of some help to start off with. We have two different pens with chickens in addition to a small pen with two young roosters in it that were waiting to be sold. Our boys recently (about two weeks ago) bought 4 new hens. We noticed one hen was making a funny noise and as a couple days passed the noises were getting worse and a little runny nose and sneezing type stuff going on. She has recovered but two other hens in that pen are now sick. We moved them into quaranteen in a small pen on another side of the property and then scoured the pen they came from. Last night I noticed that one of our young hens (20 weeks old) is now sick and making gurgely noises. This morning one of the roosters in the small pen is very sick, he is laying down and won't get up. I think he is dying as his body and legs seem stiff. All our chickens have fresh clean water, good fresh food rations and their pens get cleaned regularly. We use shavings in nest boxes and hay on the floor of the hen house and the outside pen areas are dirt. What can I do for our chickens??? I feel awful and don't want to lose them all. We have 25 in all. I don't know that it is bronchitus but from what I have read I think it might be. Any help, information or suggestions you have will be greatly appreciated.
