I will be putting my 6 week old chicks with my 16 week pullets...i'm concerned about the food situation...so i have benn doing research on my options...seems the best option is flock raiser with a dish of oysters on the side for the soon to be layer to eat..and once they r all laying i can change back to layer pellets or mash...ANYONE USE FLOCK RAISER or have any suggestions on the feed situation...NOTE: i have limited space and cant section off the chickens with their proper food.
