My brother has what appears to be a white rock hen. she is 2 years old and he only collects eggs every few days or so since his wife is preggers, they won't eat farm eggs until after she delivers (under Dr. orders) Anyways, for the past few weeks he goes down to the coop about every 4 days and there is 7-8 eggs EVERY time. They are huge eggs to, at least xlarge if not jumbo. How is this possible? She lays an average of 1.75 eggs per day. I thought they couldn't do that. Before you ask, he has no other hens. Just one hen and one roo. There is no artificial light provided and they are contained and feed layer pellets.
