BR's or cuckoo marans.. cant tell them apart!

[birdbrain5]

i hatched barred rocks and cuckoo marans at the same time.. my plan was to keep an eye and take them out as they dry and seperate them. over night i have 6 hatch and now i cant tell who is who! is there any distinct way ii can tell them apart?
