They can survive without food or water for about 48 hours. I must say, though, I provide food and chick starter almost as soon as they are fluffed up and they are nearly always hungry,
me too especially for broody moms-chicks hatch and they keep sitting to keep hatching so it may bew afew days before she actually gives up on the eggs that dont hatch-I dunk their beaks in water and food and leave them with momma-I watch them scurry out from under her take a sip of water and grab a morsal of food and run back to snuggle! cutest dang thing ever!
