Well, they aren't Cuckoo Marans, for one thing, certainly not pure ones. They'd look almost like Barred Rocks if they were, just with more chevron-like barring. They only have the barest hint of barring at all. They have to be mixed with something else.
They both seem to be males, though, certainly the first one is without a doubt. Second could be a pullet, I guess.
They're way too young for spurs, Auntie. They'd have to be close to 8-10 months old to really have spurs.
