I pay about $19 for a 50 lb bag of Kalmbach flock raiser crumble. Non-GMO, 20% protein. I've never had "billing" issues with my birds. And they love mash; it's their favorite "treat." Very little feed gets wasted here.
I used to be able to get Kalmbach at a farm store near my old house and I liked it very much. It's not worth a nearly-half hour drive to go to that store though.
