I see lots of people offering separate oyster shell instead of layer feed. What’s to stop a rooster or pre layer from eating out of the oyster dish? Chickens peck at everything.I also have 7 pullets and a cockerel and right now we are still feeding them grower feed. When they are more mature and developed we will start feeding them FlockRaiser by BlueSeal and we will provide the hens with a separate dish of oyster shells
