What do I do for winter prep/molting/egg laying and eggs to get me through winter?
I take a multi-prong approach.
I manipulate my flock so that I always have a set of pullets that come into lay by July or August that gets me through the first winter while the 2nd year hens are molting. (Note: in the northern latitudes, it is very important to get those chicks hatched so they come into lay by August or mid-September latest, otherwise you can end up with no eggs until spring.) So I am refreshing the flock each year. With a group of fine broody hens, who like to go into brood February through May, I have a staggered bunch of new pullets that are ready to lay through winter.
I also have an extra fridge where I've stored eggs. They can stay quite fresh with bloom and refrigerated....for about 7 months.
I have also over the years refined my flock for sustainability through selectively breeding and keeping my own "mixed" breeds that tend to be more stable layers (and pretty egg colors too). While the commercial hybrids lay like crazy, they are pretty played out by the time they are molting. By 3 years of age, most of them have died from internal issues. I like having larger eggs than the first year pullet size. That helps me keep large eggs too.
I find keeping "mutts" more sustainable. It's actually the way the old time farmers did it. Rotating flocks and keeping the best layers and healthiest. Over time, you see an overall stable flock that is fairly disease, mite, worm, free, and while aren't the super layers, do lay steadier throughout the year.
I also use fall time as time to reassess the flock and thin out the aging birds that are no longer productive. (Sorry, my land is too small to keep everyone for forever. Also, older hens tend to be mite and worm magnets for the rest of the flock). I have done everything from butcher to give away. Usually a note on Craigslist for free older hens gets me several interested persons.
I don't do supplemental lighting. I burned a coop down with an extension cord and flood lamp my first flock, years ago, and don't have the inclination nor dollars to run real electrical lines to the coop. Word to the wise, if you supplement lighting, be sure you are SAFE. Chickens stir up an incredible amount of dust that can actually ignite around hot light bulbs, let alone bump lights into bedding. Never leave a bare bulb exposed. Even outdoor rated extension cords can pose a hazard.
One winter I tried little battery charged closet lamps, which did help. You only need enough light to read a newspaper at roost height. However, that became a hassle to keep those rechargeable batteries charged every other day (or spend a small fortune in regular batteries). One night of darkness and you've lost the advantage. So after a few months, I simply gave it up.
I now just let my flock do their natural timing. I honestly think it is healthier for the bird to take the time to rejuvenate with molting.
I try to pamper my girls (and fellas) a bit while they are molting. I often switch over to Nutrena's Feather Fixer which does seem to help them get through molts faster. I find having a protein feed of at least 18% helps. I have supplemented with cat food, but that often is simply an extra step and expense, and my flock didn't seem to particularly like it.
I do use fall time to reassess my coops for rodents. After the fall gardens have ceased, natural foods reduced, and the ambient rodent population prolific, I find I begin to lose feed to the little beasts faster. I've tried everything from traps to herbs to, uhem, even having the boys shoot with air rifles (yes...there are that many at times). I've finally resorted to generation 1 poisons as they take repeated ingestion to do the trick. That prevents unintentional poisoning of pets and wild life.
And finally, I use the reduction in eggs as a chance to worm the flock. Be careful not to use fenbendazole as it has shown to cause feather regrowth problems. I either use Wazine or Ivermectin.
Then a good shaking out of the coops, and I'm ready for winter. I clean the coops and sprinkle poultry dust in corners. If they are really gross (which they don't tend to get as I reuse my empty feed bags as coop liners), I apply a solution of hydrogen peroxide. Make it strong (about 30%) using something like Oxyclean. It will literally bubble up that icky caked on crud on the floors. Let it sit, and it will also disinfect. Reapply my coop liners, fresh pine shavings, another layer of poultry dust, and my birds have a nice coop for winter.
I deep litter in the runs, pulling coop shavings into the runs. Fall and Spring, I let my gardening friends know I've got more "black gold" for them. It's amazing how many will show up with smiles and buckets to clean my runs for me. (That Tom Sawyer streak of mine).
Overall, that's what I do.
