Easter egger with barred gene

[AussieJen]

Hi Folks, I'm after some advice please.

I have 7x 2-week old chicks hatched from bought Easter Egger eggs & happily co-parented by 2 d'Uccle broodies.

The father is an Australian Araucana roo (pure white from 2 lavender parents).

3 of the chicks hatched from Cuckoo Marans eggs. Given barring genetics (solid coloured roo over barred hen = barring passed onto males only) I was pleased on hatching none of the chicks had white head spots as I'm in the burbs and can't keep roosters. Next day I noticed one had a faint grey smudge on its head, and now at two weeks I'm starting to see stripes on the wings.

Here's siblings and Mummas

Head "smudge" on day old chick

Stripes now appearing on wings.at 2 weeks

What are opinions on whether this is a roo? Happy to wait and see, just curious about the genetics.

Thanks!

If you have a solid colored roo over a barred hen, then those are cockerels. Absolutely no doubts. I'm not sure about that 'smudge', usually its a well defined dot... So I'd give it a tiny bit more time to make sure. If their barred though, their male.
