Hi, yes, I read all of those, thanks.
I think the problem was me, not the eggs. :/ Temp was steadly, but the humidity was all over the place.
I'll give the Marans eggs another day or 2, but I think they are goners..
My sticky chick is doing fine, feisty little fuzzball now.
So, assuming the last 3 eggs are not viable, my hatch rate for the 15 shipped eggs is 26.7%. Bummer, but at least I have 4 adorable chickies.
A dear friend & I did the same thing with shipped eggs.. 0 zero percent success.. They were literally tossed so hard from truck to truck. More than half were broken.. We did have one make it but then died.. It was so sad..
