Yikes....I think I'd be a little more concerned about the ratio of roosters to hens. Too much competition and they can end up over-mating the hens, almost literally to death!
I don't see a huge problem with feeding them starter (although some may disagree with me) but since you have a mixed flock and they are at point-of-lay already I think I'd be switching to either all flock or grower, making sure there's oyster shell as a calcium supplement for the girls.
