Can you tell Cuckoo Marans chicks from Barred Rock chicks?

[l'abeille]

I'm trying to figure out how many surviving chicks of each breed I have, but I can't figure out which are cuckoo Marans and which are the Barred Rocks. They are about 2 days old now, from McMurray.

Thanks for any ideas!

The barred rock chicks will have yellow legs (girls have a dark streak down the front of the leg,) and cuckoo marans chicks will have a light pinkish white leg.

Oh dear, they all have slightly yellowish pink legs with varying amounts of black. Any other differences I can look for?

That's the biggest difference until they are fully feathered. Sorry
