I feed my chickens dog food every once in a while. They seem to like it more than chicken feed. It has some of the same stuff (rice, corn, wheat) plus some mystery meat. The ingrediants list "Meat and Bone Meal" as the first one.
I buy typical 4-way chicken scratch and a gamecock mix called Piñata. I mix them half and half in a bucket for all my chickens, young ones included. Is it bad to feed the young ones game cock mix? I try not to feed it to the small chicks, I try to give them starter or laying mash... but the mama hens try to feed them the good stuff from the gamecock mix.
