The midnight majesty marans looks like it has a hint of barring, versus spots. Might have a touch of Cuckoo marans in him/her??
EDIT: I see later someon posted they have BR in them. I think there is a hint of barring - but it could also be a passing phase in a juvenile molt. I have had (actually, do right now ) a couple French BCM pullets who look like they went to a feather dresser and got 'frosted'.
Unfortunately, I am really thinking that it looks like light cuckoo type barring (i.e. not crisp like BR), maybe a 'muddier' barring given the cross? Again, though, not a hint of waddles. So....I say wait a couple more weeks, and you will probably know for sure then.
Yes, my marnas have always seemed to pop combs early, but
@RebeccaBoyd would be more experienced with them. I think it has a roo stance in the first pic...BUT no waddles, so I think 'pullet' for now
