I just got my first egg this morning from one of my RIR pullets at 18 weeks! Since them I've been feeding them a grower/starter mix with amprolium in it, along with whatever they find in the yard, BOSS, and the occasional treat of eggs or fruit. They really only eat their food in the morning and at dusk. Should I switch all 5 of them to the 16% layer now? My 2 other RIRs are doing the egg squat.
