They don’t like the oyster shells even though I already offer it. I’m asking about the meat feed for my roosters as I don’t really plan on taking them off layer feed. At least until they decide oyster shells isn’t so bad.I would go with the all flock feed so that all of them can eat it. Oyster shell can be in a container of the side that the laying hen's can freely help themselves to as to what they need.
Have you ever though of growing some microgreen's for them? I'm thinking about doing that myself. I heard that it's good for them and it cut's down on the amount of feed that they need so that you don't have to buy as much.
