I have Marans chicks from the assorted Marans bin. They could be either French Copper Marans or Midnight Majesty Marans from Hoovers Hatchery. My question is will I be able to tell which one I have? They’re about 5 weeks old, solid black and have feathered legs and feet. I’ve read a black copper lays darker eggs than the other. But I was hoping to figure it out sooner that that!
