Was looking at one of those cute pics. in the magazines of mama hens leading chicks and, being a novice, wondered: If one chooses to let a hen hatch/raise bitties, how does the hen get food and water if she's sitting on eggs? Once they hatch, how does one arrange for the hen to eat layer mash and the chicks to eat chick starter if they're together? Or do they both eat Flock Raiser or something?
