I have a very small mixed flock of 7 heritage breed hens that are around 8 months old. They have artificial light of around 15-16 hours a day, heated water and a consistant and good feed supply of layer mash. Up until 2 weeks ago they lay around 4-7 eggs a day, but have stopped laying. One morning I went outside and there was only 1 egg, then the next day 1 egg and finally no eggs? I have given them 2 weeks now and no eggs? I know the weather here in W.V. is terra bad the last few weeks but I have friends that there chickens are still laying. Does anyone have and idea of what is going on?
