I being a newbie probably did this wrong and apologize BUT all our girls get/got the same food once they were put in the coop together. It wasn't to hurry them to lay just no way to adequately separate the food source and will address that problem with the next coop build. The littles have done very well growing up to be BIGS and all but 1 of the 5 littles is laying regularly. I did the same thing with the now bigs...they got layer crumbles from the time they went to the coop at about 10 to 12 weeks. They rarely ate "food" they foraged for what every they wanted. The real food eaten came after the first egg was laid. The Barred Rock at 18ish however the orpingtons and silver laced Wyandottes were around 21-22 weeks.
