OK...is there a way to combat frozen eggs? My girls just started laying Friday and already I've lost two to freezing! They seem to be laying around 10am, and I don't get home from work till 4pm or so...it has been sssooooo very cold out that the eggs are freezing within a couple hours. Is this just something that we northern chicken keepers have to live with during the winter, or are there some tricks to getting unfrozen eggs?
