It could be what you have them on. I never have a problem, but I buy large flake pine shavings that have very little dust. I would think maybe your bedding is dusty? Or, if they are diapered and no caged I have no idea.Has anyone found that keeping chickens indoors is bad for their lungs? One of my girls has been sniffling a little lately and I'm not sure if it's just because they've been inside.![]()
