You only feed scratch and not a complete feed?No oyster shells provided, and the chicken scratch is a mix made up by the feed store, let's see, it has crushed corn, millet seeds, wheat seeds, sunflower seed's, pellet's with a light touch of molasses applied, been feeding them the same scratch for about 3 years, oh, recently a coon reached in a cage and ate all the chicks in it, so I mixed the rest maybe 20# of chick starter in with the scratch.....ps. the racoon went to racoon heaven since the ordeal. Ms. still allows us to have shotgunz.
