Where are my green eggs?

[fshinggrl]

I have one Easter Egger hen who lays green eggs. She laid them last fall. The chickens are 1 year old now. She took a break ALL winter, even though I was well supplied with eggs. I have ten hens. I get a maximum of 9 brown eggs a day. I average about 6-8. Where is my green egg??? She does fly out and back in the coop on her own but there is no hidden nest. All her eggs last fall were laid in the chicken coop and if I am not mistaken, she was the first hen to lay of my flock.

Help!
