I was wondering if anyone uses lighting to extend their egg laying season? If so what type of light do you use? Does this seem to shorten the life expectancy of the hens or do them seem to be less healthy if you do this? Has anyone tried alternating lighting so that all your hens aren't laying eggs for the same amount of extended time? (Another words all your hens aren't exposed to the light for the same amount of time/months). If you don't use lighting can you still get eggs regularly with 8-12 hours of light?
