I just researched the protein contents of barley and oats. Oats are way higher but I hear chickens don't like them? I know they never ate them the few times I bought scratch mix. Last winter I fermented barley for their supper but last winter I only had layers and one roo... I'm heading into this winter with a more varied flock that has 5 very big, healthy young breeders/chicken dinners So, my question is, which grain or grains should i get in addition to their breakfast pellets and why? Please note that i will not use corn or soy as my feed store cannot guarantee them to be gmo-free and it's bad enough that the pellets likely contain that garbage. Thanks!
