I am getting back into chickens after about 15 years, I have a question regarding feed. Obviously you feed chick starter when they are little, then stay with starter or grower until they lay then layer feed seems to be recommended. Though it says not to feed layer until birds actually lay as the high calcium can harm the birds kidneys, my question is if I switch to layer ration eventually is it safe for my 1 or 2 roosters to eat or will it damage their kidneys as they are not using the calcium to produce egg shells? Also could I feed something like All Flock and have a separate oyster shell feeder available for hens to pick at if they need calcium? Would this be detrimental to the hens as opposed to layer feed?
