I have 9 Black Australop chickens. I installed a lightbulb to get them to lay thought the winter. It was working for a while, with them collectively laying around 4 eggs per day. However, I had a timer malfunction a few weeks back, and since then they have not been laying at all. I don't know if it has to do with the cold tempatures, or the fact that the foot of snow on the ground has limited their forage. (they are free range). It might also be that they aren't tricked by the lightbulb anymore. If this is the case, should they start laying again once the days grow longer? Any suggestions to get them laying again ASAP would be greatly appreciated. Thanks.
