I have chicks coming in a few weeks, for the first time ever! They are quite an assortment, some cornish X, some future layers, some assorted roosters of heavy breeds for meat...can I feed them all the same thing until they reach either eating age or laying age? Or should the meat birds get something different? I seem to be reading that chick starter is fine until hens start laying, is that true for meat birds as well (I mean that chick starter is fine until they become meat)? Or is there some intermediate feed that meat birds switch to after the chick feed? I wasn't really planning on keeping meat and laying birds separate, but will if necessary. Thanks!
