I'm hatching Golden Cuckoo Marans this weekend. I have a question about Maran egg color. Is there a difference between the different types of marans? Do Black Cooper tend to lay darker eggs than other kinds of marans or is it all marans lay similarly dark eggs? (darkest at the beginning of the laying season then gradually getting lighter til they rest in winter) One reason I want to know is a friend's dad is taking my maran rooster(s). They will get to go live with his 30 hens. He has been thinking of getting BC Marans, saying they lay the darkest (darker than other marans). Is this true?
