I have 4 chickens that are just over a year old. They've been laying for quite a while. I also have 2 EE chicks that are just over 12 weeks old. This morning, I got 4 full size eggs, then one tiny brownish/ blue-ish egg. Is it possible that one of my EEs is laying at 12 weeks? I can't think of any other way to account for it. Thanks.
