I just got my chickens last Sunday. One of the hens seemed to have a runny nose the next day, but she has been acting normal--eating, drinking, pooping. Today she is sneezing and coughing non-stop, but still hopping around and eating. Her eyes are very shiny. Her poop looks different from that of the other hen, but I'm not sure what chicken diarrhea looks like. It's not totally runny, just wetter than the bigger hen's. (There are only two hens in the coop and run, the rest are pullets and are in a chicken tractor.) What should I do? Do chickens get colds that pass just like people? I don't have money to take her to the vet or buy any expensive treatments, but I also don't want to let her get sicker if there is something simple I could do to help her. Should I worry, or just wait it out? Are they other symptoms I should watch for?
