Hi there... I'm new to chickens. I have 9 week old chickens that I stupidly let out in the rain a few days ago. Now 2 of them have occasional coughs/sneezes. One of them is sneezing a bit more frequently than the other and also has a small amount of clear nasal drainage. This one also has a bit of rales when sleeping, though not when awake. I read through several articles on respiratory illnesses in chickens and they all sound like fairly horrific affairs. Can they just have a cold from a less pathogenic bug, so to speak? All of my birds are still eating well and are still quite active (including the two occasional sneezers). I do think letting them out in the rain is the probable cause as I'd never heard them sneeze before and they probably got a bit chilled from what they are used to. Thanks. Appreciate all thoughts!
