Not sure, but I think this is the Cuckoo Maran. I know the extra chicks are typically roosters but any thoughts? When he first arrived he was really black, but now he's 2 weeks and looking more grey. So does that mean roo? I have nothing to compare him too since I've never had marans. Also when I first got him I tried sexing by feathers based on primaries and covert length and they were all even so I assumed a roo. I don't know if that even works for this breed. But I wanted to see. Any thoughts? Oh they are now 2 weeks and 1 day from arrival. Thanks!
