Chicken stopped laying?

[GimmeCake]

I've noticed I don't get green eggs anymore. I only have one EE, and she usually lays. But no eggs for the past week or so. She seems fine.

Any ideas on what's wrong with her? It doesn't seem to effect any other chicken.

I also have 1 green egg and she stopped laying. Then I found a pile of green eggs hidden under coop. Be sure to look around.

Or it is possibly moulting. Mine are.
