I don't get many eggs yet as my girls are young and so is our routine. It has been cold here the past week. 9 degrees to 30 degrees. I have found a few eggs that must have had a chance to freeze. Maybe overnight. They want to lay in the corner of the horse stalls. Question is..what are the uses for theses possibly frozen eggs? What's the limit for use? A day or two? Right now freezing can happen in hours. I'm trying to bribe them to lay inside where they'll be good til I find them...but ..you know how they can be.
