The one laying hen lays her egg at ~8am every day. That is also the time the light turns on in the hen house. I hope the other four, when they start laying, will hold to her schedule. It is nice to go out at 8:15 and pull a still hot egg out of the nest box.
We got an extra large egg the other day. My son Jack took one look at the over-sized egg and told me that it was double yolked. I scoffed, having never seen a double yolked egg. He, of course, was right. Dads are dumb. :P
