I have 25 RIR hens. I get about 20-25 eggs per day. Mine were born March 12, 09 and started laying in July/August. Another thing, they will start out as small eggs, or "pullet eggs" and gradually get larger.
SO STAND BACK, THE EGGS ARE COMING!! I don't try to sell the ones we don't use, just give them to some elderly neighbors who really appreciate them.
The funny thing is, some of the egg shells are very very light brown, some a really deep brown.
One thing for sure, I sure do love/spoil my chickens.
