How much light do I need in the coop during the fall/winter months?

[sshavney]

We are trying to outfit my new 8x12 lofted shed/coop for the fall/winter low light months to keep the hens laying as normal as possible. The shed faces south and has two windows on the front. I have 9 5wk olds that will be sharing the coop (separated of course and with a heat lamp). The adults are pretty much free range, and will only use the coop to lay eggs and hang out. I know I will need to put roosts in and nesting boxes, anything else I might be missing?

Enough to extend their days to 14 hours if you want them to lay through winter.
First year pullets will lay with no extra light added.
