Our layers stopped producing this past fall, so we ate them. Don't expect the quantity and quality of meat you get from store chicken, but it was edible after chopping it up fine enough. We also pressure-canned some, and that seemed to make it less tough.
Chickens FTW.
I had a friend that raised fighting cocks. He told me that chickens lay according to the amount of day light and will leave off laying when the daya are shorter. So he kept a light on and they laid all year long.
