My Easter Egger stopped laying

[jophoto]

She hasn't laid for a month. She started in August, and was laying a green egg a day to an egg every other day, and now has completely stopped. The other EE (that lays a cream colored egg) is still laying.

Any ideas what is wrong? She looks/acts healthy otherwise.

All my other hens are laying wonderfully.

Is it the light? Why would just one drop off?

My hens are not laying right now either. I have some that are about to become of age in a couple more weeks, so I am curious to see if they start laying. Last year when my young chickens became 6 months, they did lay through the winter. But my older ones stop laying, and start again in February.
How old is your EE?
When my EE molts, it is so obvious. She loses her feathers and looks quite silly. My RIR's only lose a few feathers at a time, and do not become completely featherless like the EE and my game hen do. On them, I'll notice, hey some tail feathers are gone, then I'll see, hey some neck feathers are missing.
