Do you have any idea how many people are concerned for their chickens cause they have a runny nose, sneezing, wheezing, eye infections and raw throats on the outside? A LOT . Do you have any idea how confusing this is? Everybody has a different idea of what it could be. Do you know how confusing it is when somebody says you have to kill your chicken to get rid of the problem. Or how emotional it can be to even have to sit there and actually think about how your favorite chicken is going to have it's head cut off tomorrow. Then you go out and make sure every body has plenty of water and the young hens walk right up to you and talk to you. Then you go back to the internet searching for a way to save your chickens. Even the ones that are not sick. I have a headache. I just want someone to tell me that I don't have to kill them. Please tell me that I don't have to kill them. From what I have read all over the place, most everybody has Coryza. And if everybody killed their flocks that had ever been exposed to coryza, 95 percent of the backyard chickens would be dead right now. Can you help me make a final decision? Can you help me save my chickens or am i just desperately looking for a cure that will never show up? Will the chickens always be sick to the point that they have to have antibiotics all the time? How do you know they have Coryza if you don't have a vet test a chicken. Can't chickens get sinus infection from regular bacteria in the coop? Some sneezing some not. Some with eye infections some not. What if your older(2 yrs) chickens are getting sick before the young (15 weeks) ones? What if what if. Some say the heat and humidity has caused sinus infections? Can it be that simple?
