I went to TS and purchased a blue swede baby and a khaki Campbell baby. The blue is vomiting! They just got them in today, and the guy who runs the chick days at our store said its due to stress. She did it once when i picked her up, and the other times she was in her tank. the first time it was all food, but the last three times have been clear bubbly liquid (I'm assuming water). I have noticed when she drinks she puts her head straight in the air and holds it there like shes having a hard time getting it down. Should I be worried about blockage? She has vomited about 4 times since I bought them 5 hours ago.
