Do they have their own coops? If so put in in the older girls coop. I leave oyster shell available 24/7 but some people do only put it in once a week but I don't keep track of who needs it and they can get it whenever.I'm glad you said that, cause I'm over hear racking my brain on how to keep him separate at feeding time, LOL!! Now I just have to figure how to give it to my older hen, and not the younger ones, because they all free roam together.
