I've been busy designing my coop and have hit a bit of a road block. I live out in the middle of a corn field in Iowa where the winds are very strong. I'll most certainly be insulating my coop and am considering a heat lamp for those exceptionally cold nights. My biggest concern in this: How do I keep the eggs from freezing? I leave for work very early in the morning. I won't have time to gather eggs till about 3 each afternoon. My wife doesn't go to work till later in the day but has to get the boys ready before she leaves. What to do on those really cold days when the eggs WILL sit in the coop for several hours? It's not uncommon for the highs to be in the single digits several days in a row with night time lows well below zero. Wind chills in my area can hit -50 or colder several times each winter. What do you northerners do to keep eggs from freezing? Heated nest boxes? Any suggestions would be greatly appreciated.
