Hi All! My five girls are in an outside coop and the run is filled with sand. I noticed a lot of them sneezing sometimes, but they don't have any other signs of respiratory anything. I have a young Polish who, for the past months or so, has sometimes breathed through her mouth, sometimes not. Today she yawned five or more times in a row, but she's active and eating and drinking. What do you all think? Is everything normal? She tends to breath through her mouth if she's nervous as well.
