If they are coopers they will have cooper on their necks
And Marans can lay lighter eggs but they don't call them show quality unless they do lay dark eggs
Ps there is dark egg laying lines and light egg laying lines
Frequently the coppers will not have the copper on their necks. They would still genetically be blue or black copper, however. The copper hackles come from breeding selection. Not sure how much of that the hatcheries do. I've also read that hatchery Marans will not lay as dark as from a breeder who is working towards dark eggs. Let us know when they grow up and start laying how they turn out.
