An All Flock type feed, or Flock Raiser. It's high protein, & great for all ages, & genders. Just gotta be sure to have a calcium source like Oyster shells in a separate container, or feeder for the hens. They know how much they need, & regulate on their own.Yikes, I just always gave it to all of my hens. I had no idea it was specific to certain hens. So, if I have a flock with hens and Billy, what is the best feed you would recommend? I really can't separate their food sources.
