I am getting some eggs this week from someone local. They have a frizzled columbian wyandotte rooster and various hatchery hens. One of the hens is a black copper maran. Despite being a hatchery bird, the hen seems to be laying between a 7 and an 8 on the color scale. How much washout can I expect in the egg color of their chicks? Will they still be darker than average or could it be luck of the draw? Also, would I be correct in assuming a 25% rate of frizzled chicks?
