I recently raised 8 pullets into 8 beautiful hens and 5/8 of them have started egg laying. They've been laying for about 3 weeks now. I walked outside to a surprise this morning when a saw this monster of an egg in the nest. Which one could've laid it? I have Rhode Island Reds, Barred Rock, Buff Brahma, Golden Sex Links, and an Easter Egg. I put another egg beside it for comparison.
