Hi. I'm a newbie chiming in. Thanks for this thread and the open discussion. This is all very fascinating and thought-provoking.
I was thinking about planting fruits like blueberries, bush cherries, grapes, rasp/black berries ect. for them to be able to add to their feed in take or even the human harvest and add to their feed, either way.
I already have two dogwood bushes near our run. The girls LOVE the white berries and I know they are safe. They are not as crazy about Schubert choke cherries. They get lots of kitchen scraps and weeds, too.
As much as I want to give my girls lots of fresh, unprocessed food from my own yard or nearby, The University of Florida says
Laying chickens require a completely balanced diet to sustain maximum egg production over time.Inadequate nutrition can cause hens to stop laying. Inadequate levels of energy, protein or calcium can cause a drop in egg production. This is why it is so important to supply laying hens with a constant supply of nutritionally balanced layer food. Feeding whole grains, scratch feeds and table scraps will cause the birds diet to become imbalanced and inadequate.Many times these imbalances can cause other problems like oviductal prolapse. Prolapse may occur when the bird is too fat and/or an egg is too large and the bird's reproductive tractis expelled with the egg. Prolapse usually causes permanent damage to the hen and is fatal in many cases.

I'll keep tossing weeds, kitchen scraps and berries into their run and let them munch on whatever they find when they are free, but I'm very nervous about replacing their diet entirely with what I can find for them. The alternative, I suppose, is studying poultry nutrition, making the best homemade feed I can and tracking the results.
My theory is that our backyard flocks produce eggs based on factors other than available light hours.
You've probably already read all the research that's out there, but for the rest of us The University of Florida says
There are numerous factors which may adversely affect egg production in backyard chicken flocks. If a drop in egg production occurs, investigate the cause by answering questions that followalso refer toTable 1 andTable 2, sick and recently dead birds to a state diagnostic lab, and/or consult with your County ExtensionAgent or a veterinarian.
- How old are the birds?
- How much feed are the birds consuming daily?
- Has the level of feed consumption changed lately?
- Has there been a change in the type of feed used?
- Is the feed moldy?
- How much light do the birds receive daily? Has it changed?
- What is the light source?
- What is the condition of the poultry houses?
- Are the birds getting enough clean water?
- What is the condition of the birds?
- How active are the birds?
- What is shell quality like?
- What is interior egg quality like?
- Are there any signs of disease?
- Are the birds crowded?
- Are there any signs of parasites?
- Do the birds have access to different plants?
- Have any pesticides or herbicides been used in the area?
As for light, they state,
Hens need about 14 hours of day length to maintain egg production. The intensity of light should be sufficient to allow a person to read newsprint at bird level. The decreasing day length during the Fall and shorter day lengths in the Winter would be expected to cause a severe decline,or even cessation, in egg production unless supplemental light is provided. When production ceases, the birds may also undergo a feather molt. Hens exposed to only natural light would be expected to resume egg production in the Spring.
I really think the decline in egg production had a great deal to do with stress from being exposed to the winter elements.
This makes me wonder if the hens who receive supplemental lighting are benefiting from the supplemental heat.
