I recieved 26 babies from mcmurray hatchery few weeks ago. 2 of the babies died few hours after arrival. It was cold during their shipment and I believe they were smothered by the other chicks. I have one that is just not growing or as active as the others. She does eat and drink, I have electrolites in the water and they are on chick starter. All the other babies are very active and growing fast. But the one looks like it has hardly grown at all and she is not quite as steady on her feet. Is there anything I can do to help her improve? Thanks
