Every day I hear an occasional sneeze from my flock. It's not always the same chicken. Is this normal? Do chickens sneeze like people or is this a sign of something else? I have a Golden Comet and Barred Rock 4wks old 1 Welsummer, 1 Buff Orpington, 1 Barred Rock, 3 partridge cochins, 2black cochins, 1 polish all 6 wks all are together they are all healthy and show no signs of sickness otherwise they all have clear eyes and no signs of runny noses eat and drink well poops are normal active during the day, with occasional naps sleep well at night I read something about dry air and maybe needing more humidity? We're in the mountains and it is really dry here, could that be it?
