We are in NW Louisiana...not really even Fall yet...ut we have had a couple of exceptionally cool nights...we were 95 degrees a couple of weeks ago and have gone down to upper 30's twice in past week. We added artificial light in coop last Friday so they are getting at least 14 good hours of light. Out of 8 hens..we were getting about 5 eggs a day and then all of a sudden none.....we have checked for snakes and other outside influences and have seen no evidence of anything...these hens were all hatched in early 2011...so they just started laying regularly about 2 months ago. How long with the artificial light can we anticipate before we get an egg from at least one of them/
