For the moment I have given up on shipping marans eggs. I will only sell chicks this season. It seems that they do not fare well in shipping. Every other breed I have, including ducks does well when shipping eggs, but for some reason the marans hatch rate goes to pieces. They hatch everywhere from 19 - 23 out of 24 here. Ship them and that goes to 0 - 4 out of 24. Anyone else out there experience this problem?
