From my understanding there all kinds of pro's & con's about choosing medicated feed or not. Flip a coin. If you are Sure your chicks are as healthy as possible, I wouldn't use it & if you hatch your own chicks I wouldn't use medicated. As far as starter feed, it is better for younger birds because it does have added nutrients and doesn't have the calcium egg feed does. To much calcium can lead to problems in younger birds. It can cause kidney stones as well as other problems.Young birds don't need it. If you're adding youngsters to your existing flock, I would use starter feed for 8 weeks and just make sure I have added calcium available for my egg layers. Crushed oyster shells work fine for me. I also give them a treat of oatmeal & milk. I use instant, add the milk in a plastic cup, microwave for 1 minute and let it cool. It pops out of the cup like a cake. My older girls love it and devour it before the little ones can get near. I don't think the starter feed hurts the older birds at all.
