I was for a while convinced that I had a male and a female, now I'm not so sure , my last hatch I only got one serama and he was visibly male very early on, there are about 6-7 weeks old I think. They hatched in maybe early october.

I'm mostly sharing these photos to show how beautiful they are and as I have NO idea on colours of Seramas I was wondering if anyone could take a guess as what they will look like?

The last Serama cock I hatched, was very yellow with a few black stripes which I have noticed is a common colour for new chicks, these two nothing like it and he is now a stunning young noisy man. I'll throw a photo up of him too.

So considering his colours now are so dark, any ideas on these two?
Thank you.
The one with the tag is presumed female, the other presumed male but hard to tell..
