Barred Rock Roo or Hen?

[Shadycreekturnaround]

I picked up a mix of pullets from a friend. A turken, a bantam, two Brahma mixes and a barred rock.
Fast forward a few weeks, and three of them have started crowing, the turken, bantam, and one Brahma.

I only have the one barred rock in the group, so no others to compare coloring. I have a feeling “Gemma” is a roo too, but really hoping it’s a hen

What are your thoughts?

Sorry, I think it's a cockerel. I think I see some pointy saddle feathers coming in and the lighter coloring suggests it might have double barring indicating a male.

Do you know how many weeks old approximately they are?

Bummer, I had a feeling. It’s the nicest one of the bunch too

How old? Looking like a cockerel, but I’m not sure depending on age.

Yeah I think it looks like a cockerel but how old?

My best guess is 16-18 weeks old.
I’ve had them for about 8 weeks now.

Unfortunately that is without a doubt male, he's double barred. Double barring can only happen in males, the barring gene is carried on the sex chromosomes (Z) and male chickens (ZZ) can get two copies while females (ZW) can only carry one. Having two copies widens the white bars, double barred roosters look like white chickens with black stripes while single barred hens look like black chickens with white stripes.

Males end up looking more grey with double barring.
