I just read a message that said 'never give lay pellets/crumble to chicks because of the calcium'. My mother hens and chicks free range with all the other chickens. They all eat the same lay crumble, whole oats, and scratch. I have tried to separate moms and babies and feed them chick starter. The hens scratch the starter away or call the chicks away from the food. I have been raising chicks this way for almost two years. My first chicks are very productive laying hens now. What problems would show up because of the calcium?
