I have 6 hens no roos, and i have 4 large breed chickens, anyways i was using crumbles, but my large breeds kept knocking the food bowls over so i switched them to pellets so far no spills, and they hve been on it for week, but im worried about the bantams since pellets are bigger and they are small birds their game hens, so should i get them a bag of crumbles? Thanks
