Cuckoo maran sexing

[SLChicks]

I have 2 chicks that are coming up on 5 weeks old. They were sold to me as cuckoo's but look to be maybe australorps? They seem to be developing differently. I'm curious if one is a Cockerel so tried to get pics of them together for comparison. The last pic of just one chick is the suspected roo. Any insight would be much appreciated

They don't look 'cuckoo' colored at all to me, so the chick with the larger comb could be a cockerel.

Thanks for the insight Mary! Are you saying they may be a different breed?

I just tried and failed to find pictures of chicks the same age as yours, but it seems to me that their should be barring on those feathers, and I didn't see any.

Well, I got them at tractor supply so totally possible I got a different breed. Hm wonder what they are then.
