Sexing Cuckoo Marans x Black copper marans chicks

[bugmom92]

I have 5 chicks that my broody Buff Orpington hen hatched for me. The eggs were layed by a couple of Cuckoo Marans hens and the rooster was a Black Copper Marans. I have read conflicting information about sexing them. I'm pretty sure I have 3 of something and 2 of something else...but not sure which are pullets and which are cockerels. They are 3 days old. Any help will be appreciated!

HI sorry, i know this post is old, but did you ever figure out how they're/if they are autosex?

Almost any non-white, non-barred male over a barred female will result in sex linked offspring (black sex links). Female chicks will be solid black, male chicks will have a white/cream spot on the head. The OP did have sex linked chicks, 2 pullets and 3 cockerels.

An excellent thread on sex links of various kinds can be found here if you are interested. The first post contains most of the information you need.
