I have a number of hens that should be laying eggs. We've had some pretty cold days, but others I've talked to have had snow and are still getting eggs. I haven't gotten a single egg since before Thanksgiving. I've feeding a mix of Dumor Layer pellets and scratch grains. They get collards and cabbage from the farmer near by. They free range, but not often, as it's often just day light when I leave for work, and dark when I get home. I think about 22 laying hens, but not a single egg! Any suggestions besides whole frying or boiling?
