Hey all! I've had my chickens for about 3 weeks now (all purchased as chicks, though a couple were probably a week or two older than the others at the time of purchase as they're much larger). I brought them outside for the first time today and they're sneezing. At least, that's the best way I can describe the noise they're making. It's a high, short exhale noise. I've never heard them do that before when I had them inside and am trying to gauge whether I should be concerned. Any advice is much appreciated!
