This isn't an emergency, but I think one of my white rocks either has allergies or a cold. I can't post a sound clip of her doing it, but I will try to describe the best I can. It sounds like a sneeze, with an inhaled gasp at the end. She is acting fine, eating fine...just the darn sneeze! No ooze either. None of my other girls are doing this or have done this. Any ideas?
