I am in south Ga and my hens are about 16mos old and they have been laying fine until a cold front came through about a week ago and now they have nearly quit. They have already been molting and laying pretty well through it, (they're actually about finished molting) and I've also had a light on at noght for about a week now and it still isn't any better. I don't think I have ever had any completly quit all of a sudden like this. Anyone else?
