I just picked up my box of chicks from My Pet Chicken at the post office...YAY! 20 of the 22 arrived peeping and healthy...one died in transit, however. The other one is alive, but doesn't look very good. She is mostly just sitting there trying to sleep, not eating or drinking, and doesn't have very good balance. She keeps on falling backwards and is getting jostled by the others. What should I do? The others are eating and drinking (electrolytes in their water) and the temp seems good for them.
