I have a flock of six pullets, age 4-8 months. A buff Ameracauna, a splash Ameracauna, a black Ameracauna, an Olive Egger, a Silkie and a huge Cochin. I have been feeding them Purina crumbles but I know that many BYC members feed something like Scratch & Peck’s organic, non-GMO, corn-free feed. My question is, are there actually benefits to spending the extra money on this type of high end feed? I don’t need corn-free feed (and don’t really understand why chickens would need it) because I actually feed my chickens cracked corn as a treat. Do you buy one of the more expensive, high end feeds? If so, why? Or do you stick with something like a Purina feed? How come? Thanks for any and all feedback.
