Marans lay varying colors of brown eggs. Laid eggs are darkest just after a molt. When they get close to going into a molt, they are lightest. Those that lay the very dark eggs have been culled extensively to keep only the darkest layers. If they are hatchery birds, most likely this has not occurred.
This is from the
Marans Chicken Club USA site:

IMO, you have Maran chicks. The quality of egg color may be in question. You may have a black Maran in there from the genetic mix. Once the chicks get bigger, color patterns will change. So the one with a clearly defined stripe will most likely get more spread out as it matures. Also, for the Cuckoo variety the hens are much darker in feather color than a rooster.
I have a couple of Cuckoo Maran hens and they are excellent mothers. They lay nice darker colored eggs most of the year. Not super dark but much darker than a normal brown egg. At times they are close to the same color though.
Enjoy.
