Hi all. I've had just laying hens and a single roo in my coop, and they eat layer feed. But now I'm going to be adding pullets (3mo), and I don't think they can eat layer feed. My local store offers layer feed, scratch, chick feed, and oyster shell. I've heard of grower feed but they don't seem to offer it. If I mixed the layer feed with the scratch, and had oyster shell on the side for the layers to peck at, would that be ok for the pullets? I don't want them to get an overdose of calcium. And I know scratch by itself isn't good enough. But I can't feed chick feed to my whole flock (and it also costs 4x as much as adult feed). Ideas?
