Fertility in these eggs has been very successful, the color of the eggs are good, but not as dark as the French Black Copper Marans. The color of the flock is good, the roosters of the flock carry the gene for dark eggs, so the chicks should produce darker eggs. A friend has some of my chicks from last year just started laying and is laying darker eggs.One picture is a last year pullet not laying yet. The bloodlines came from Charles Logan.

I've had excellent results hatching these egg, usually better than 90% hatch rate, but due to differences in incubators, etc...cannot be responsible for hatching rate.
