Sorry about the shipped eggs.
IN talking with others from the Dominique Club, it seems that a 50% hatch is normal, unless going from low elevation to high elevation. In that case, the 50% is cut again by nearly 50%, so that would only be a 25% hatch. a 10% hatch isn't very good. What does MPC say about their shipped eggs? I'm sure they don't give any type of guarantee...
I sent customer service an email explaining that I was disappointed with the porosity of the eggs and the way that they were shipped. I told them how many eggs showed no signs of life by day ten. Their response... you should've waited until day 14 to discard. We usually have good luck with the farm that your eggs came from. Good luck with your hatch...."
On a positive note... 3 of my barnyard marans have pipped. Just waiting on them to unzip!
