I have Welsummer eggs that were due to be here yesterday but haven't shown up yet. They were shipped Tuesday per US Priority Mail. The weather has gotten colder than I expected the last few days. The eggs were coming from Utah, and I live in Ohio. My question is, with this cold weather (20-25 degrees here)and delayed shipping, what are the chances that the eggs will still be viable? I would like to hear from people who have had a similar expirience. Thanks.
