TWO out of three hens stopped laying at the same time

[Macrina]

We have an Australorp and 2 Orpingtons. We have had them about a month and they are all about a year old. They were all laying appropriately within a week of getting them. We moved them to a new coop about 2 weeks ago. They continued laying without interruption. About one week ago the two Orpingtons simultaneously stopped laying. They free range during the day and seem healthy and happy. The Australorp is clearly the Alpha Chicken, but she is not picking on the other two.

Any ideas?!

Thanks so much!
