Bcm chick part cuckoo marans?

[VaultGirl27]

Is my black copper marans chick part cuckoo marans? She doesn't have the head spot and no other bars on her but can't figure what else would be the cause. She's supposed to be full bcm and looked it until she developed the stripe. Maybe the white will grow out at molt?

Sometimes black birds have white on them as they mature. Feathers molt out a few times as chicks grow, so they don't always show their adult coloration right away.

Thank you! I sure hope this is the case
