So... it's been somewhat chillier over the past week, and I've been behind schedule collecting my eggs during the day. Did you know.... at -25c/-13f eggs freeze, expand and the shell cracks to let that sticky messy egg slushy goo gather in your nest boxes if your not prompt at retrieving them? 
Moral of the story.... Don't be late for egg collecting in frigid weather!
