I have a small flock of 11 - 2yr old Buff Orpington's hens. None are broody, none are molting and no change in feed. I supplement with layer pellets and they free range all day. They laid great last year and slacked off during the winter (as expected). I have only been getting 2-3 eggs/ daily since the winter. The temps are still very mild here in central Texas. I haven't seen any signs of snakes or predators and all the girls look healthy. Could they be coming to the end of they're "laying life cycle"? So soon? Is this typical of this breed?
