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. Accept Paypal at [email protected].

I've had excellent results hatching these egg, usually better than 80% hatch rate, but due to differences in incubators, etc...cannot be responsible for hatching rate.
