For those of you in cold climates, do you ever get frozen eggs in the winter? My coop is insulated, but I'd have to guess that when outside temps are in the single digits/teens all day, would the eggs have a chance to freeze even in the coop? Of course I'd be so excited to have laying hens that I'd probably be checking for eggs first thing each morning---but if for some reason I didn't get to it in time, is the egg ruined (for eating)?
