3 of my chicks hatched last night, and they're all fluffed out and drinking normally, but they won't eat. I've put them right next to the food and tapped it with my finger, trying to make them think it was a hen pecking at the food, but they just ran up and snuggled against my hand... They're being perfectly normal chicks except that they won't eat... I'm a little worried about them. Is there anything else that usually works to get them to eat? Thanks!!!
