We have had to cancel some egg deliveries for this week. The reason for this is due not only to lower than usual production due to the winter season, but that most of our eggs were freezing and cracking in the nest boxes before we had a chance to pick them up on Sunday and Monday (when we had the coldest temps). We've found generally on the farm that -8 deg. Fahrenheit is very cold weather for all sorts of things: water pipes, eggs, and people. The livestock, however, seem well adapted to the cold since they are dry and have food and water.
The photo below some of our chickens surrounding their trailer. Typically they roam further away from the trailer but during the cold snap they've preferred to either stay in the trailer and roost or roam around under the trailer itself.
