I have three, 2-year old layers. Lulu definitely has a mild cough/sneeze that maybe started mid week last week. She has a crooked beak and only one nostril so we didn't pay much attention. Last night however, on the roost, Rose was sounding like a horn with each inhalation and exhalation. Everything else is normal in appearance and behavior. Unfortunately, we aren't able to be spending $65 for a vet visit. Do chickens ever get the "common" cold and recover? I'm an avid reader of all sorts of posts here, so am hoping the stores of terrible illness and mass quantities of medicine are the exceptions rather than the rules. What are our chances?
