I'm getting only 2 eggs per day from my 27 hens, but I don't light the coop and 8 of them are young and haven't started laying yet.
If you really want eggs all winter, get a leghorn (I don't have golden comets, but I imagine they are the same). My leghorn is in her second year, and she is laying almost every day.
Chanteclers are great winter breeds, but be prepared to watch them sit on the nest all spring and summer.
For some reason, my EEs all take long breaks in the winter (even in their first year), but they are worth it for their pretty eggs.
I like the idea of another member on the forum, "Fred's Hens". He keeps 2 flocks, - one flock is young production hens that supply eggs year round, the other is an assortment of nice breeds, what he calls "yard art". If you check out his page, he has a long article about chickens and egg production that I found very informative. Someday, I'd like to try his 2 flock approach.
