How long does it take for an egg to freeze when the surrounding air temperature is freezing? And is there any way to tell if an egg has frozen if the shell hasn't cracked yet?
My coop is not insulated, and although we check for eggs 3-4 times a day (most days, some days work prevents us from checking more than twice) there have been a few eggs that have been very cold when I've picked them up. The egg I collected tonight at 6:20 had probably been there since 1:30-2:30 this afternoon, and our temperature never got above freezing for the high outside the coop.
