Shipped eggs are always risky, but sometimes it's what you have to do if you want a a particular breed. My first shipped eggs were from California, and that was my best hatch (10 of 13), and I only rested them 12 hours. Tennessee, I got 7 of 15, and Washington State, 2 of 17. I tried incubating without turning for 7 days that time.
It is really best if other people give feedback about packing and hatch-ability. I didn't have that type of feedback for the Washington eggs, but took a chance because she had two different breeds I wanted.
You just have to be willing to throw some money away. The way I look at it, we go out to dinner every other Friday or so and spend up to $45, and that money is gone in an hour. My problem is that there are so many breeds I want to try, and I'm not that into setting up a bunch of breeding pens.
Hoping to get some necropsy results (and also a stool sample from the other sick hen) today!
