Hens quit laying

[Darcey7]

I have 6 hens, 1 Dorking, 1 Austrolorpe, 2 Buffs, 1 Easter Egger, and 1 Cuckoo Maran. they were consistently giving me 5 eggs per day all through the winter, and for the last 3 days, NO EGGS. My first thought was predatory snake. But I have kept them in the chicken house which is snake proof, and still no eggs. I find it odd they would all quit at once. Any ideas? They eat NON-GMO layer feed, and there has been no change in anything!

Has something frightened them, or are they being frightened during the night? How old are they? Could they be going into a molt?

This thread addresses the various causes:

No, they are not frightened. 5 are 1 year old, 1 is two years old. I hand raised them all. They do not look like they are molting. One of the buffs is broody on an empty nest.
