Mary, Great pictures (as usual!)....keep them coming!
Mahonri, Congrats on a great hatch!! I do take great care of my Icelandics...they are treasures and merit it...but I believe there is more to it than that.
None of the eggs I sent was more than 3 days old at shipping. I use the system I learned here on BYC to pack my eggs....individually wrapped in bubble wrap, large end up in a smaller box, inside a larger box that has more filler to keep the small box from moving, this side up arrows on the box sides. Printed label online with Delivery Confirmation. DH took them to work with him to his Post Office (Naperville, IL) and sent them from there. Naperville has more trucks to and from the processing center each day and mail moves quickly (okay, quickly is relative) compared to our small, rural P.O. Your eggs were mailed Tuesday a.m. and you had them Thursday, so they spent little time in the "system". I think the combination of all of these made the eggs most viable and then you provided the right, though at times, manic, enviroment for them. I hope my pullets, when they are done hatching out the 33 eggs they have, get the same percentage as you!
I'll look for a picture of Dreki as a chick...don't know if I have one that I will be able to identify him in as a newborn though.
