Ok , I know this may sound like a stupid question , but can 1 chicken lay 2 eggs within 1 sitting time? I have 2 Barred Rocks which had their own nest boxes if they wanted them. Each would lay 1 egg per day. Lately, Emily has Not been in her own box because I've been finding now, 2 eggs in Lucy's box. Just now I Heard the famous " egg song ", and once it stopped, there were 2 eggs! I was gone most of the morning, so I don't know if Emily sneaked in there, laid her egg, jump down , the Lucy would jump in and lay hers next to the other. I haven't witnessed Emily going into Lucy's box , but I don't know. This is my 1st year with chickens, so pardon my ignorance.
