I have 6 Red Ranger (from Murray McMurray) pullets, now at around 15 weeks. At least 1 has started to lay, large brown egg and sometimes a huge double yolker. Another is red enough that she may be laying, not sure yet. I have 3 Buff Orpingtons that I got for laying since they have higher likelihood of brooding, the RR were bought for meat but DH said keep the girls since our hens haven't been laying very well (age). Who knows, I may end up keeping the new ones and butchering the older ones in the fall. I got maybe 3 eggs a week since October to now 2-3 per day, don't really know who's laying what except that the color/size of the egg has changed.
