I have four hens, at point of lay, 2 RIRs, a Buff Orp and a Silver Laced Wyandotte. I'm getting 1-2 eggs a day, but I have NO IDEA who is laying them. There is usually a big egg and a slightly smaller egg, but the color is identical. One of my RIRs is doing the squat when I get close to her. Do they still squat after they begin laying? I've seen both the Wyandotte and one RIR go to a nesting box during the day, but have not confirmed if they are actually laying. Any tricks of the trade to determine who's laying and who's not? Here is a pic of some eggs: Thanks!
