Hello, everyone! We just purchased 3 pullet Bantam Cochins and 1 rooster from a lady about a week ago. I noticed the day we put them in the backyard one of the Pullets kept sneezing... after doing some research online and now the others have started sneezing as well Im affraid they have some type of Upper Respiratory Infection The thing is, I plan on expanding my flock of chickens and want to buy more and also raise/sell chick however since I think these chickens are infected What is the right thing to do?? I am not wanting to sell or give these sick chickens away since they are considered carriers too I have only noticed them sneezing, no other obvious signs I can detect from looking at them. some help would be greatly apprectiated!
