We got 8 baby chicks that arrived Monday, all different breeds. One is smaller than the others, has less feather growth on her wings so far and seems to sleep a lot more than the others. She eats ok, drinks, no pasty butt and normal poop. Just not sure if I am being paranoid. All chicks were vaccinated, and are on non-medicated chick started. Cleaned twice a day and the others are thriving.
