I was thinking on this subject while I was at work today, so I apologize if it's already been covered.
Perhaps the "reason" that the hens rely on the light to lay is that their body shuts down the egglaying during the winter when there is less forage. Their body goes into conservation/survival mode during the time that there isn't much grass or bugs to eat. Think of how deer and other animals put on fat in the fall and then practically hibernate during deep winter.
We supplement our birds "unnaturally" with feed, so they can be stimulated "unnaturally" with light to continue laying for our benefit.
I'm not sure how to feed a flock in order to keep up the egg production for consumption, but I imagine that the birds would be able to squeak by if they had to - especially in my climate where it's not TOO cold and there is dead grass and such. The trick, in a bad situation, would be making it worth keeping them around until they start to lay again
Just my .02 for the day
