I've heard that egg layers and meat birds need different levels of calcium but I'm not sure exactly what to feed my flock once they're off starter feed nor do I know exactly if my chicks are considered layers, meat birds, or dual purpose if that makes sense. I want to make sure they're all getting the right amount of vitamins and nutrients. I have 2 buff orpingtons, 2 EE, and a sapphire gem. What do ya'll recommend for a well-balanced healthy feed for their particular breeds?
