Only green eggs...

[Lucy4]

I have two ameraucanas; two orpingtons. I've only had green eggs for a week (I light the coop for two hours every morning so they keep laying.) I looked to see if the BO's were laying elsewhere, but I can't find any brown eggs. They're not molting. Why would the BO's suddenly stop laying?

Thanks for any insight.

It might just be the shorter darker days. Or they could just be taking a random break.
