I have 4 hens and have only laid maybe 12 eggs since this past August. At first I thought the heat and molt was to blame but their feathers grow in over a month ago. Only one girl, an Easter Egger, is laying anything at all. The weather here in Southern California is mild at its worst and our daylight, even in winter, still meets their needs. Their activity level is very low and they are spending most of their time under a rose bush.
