Your young pullets also do not need the calcium in layer feed. Their bodies are not ready to handle the extra calcium. In any mixed age or gender flock it’s best to stick with an all flock raiser type feed with a side dish of oyster shell available. I keep a feeder filled with oyster shell inside the coop (no feed allowed inside the coop) so they can enjoy at will. Vicks, young pullets, and roosters aren’t interested in it other than the occasional curious peck.
