I went out this morning to do my chicken chores, and there was a lady on the nest, and under her was an egg. We have 4 buff orps. and get 2-4 eggs a day. I just picked up one daughter from school and she ran out to check for eggs and came back with 5 more! And the lady was still sitting on them all!! Not sure how the other chickens got their eggs under her! Just wondered if this is normal, I thought one egg a day per chicken.
