Any Opal/Split Legbar chick sexing experts?

[Northstardreams]

This is an auto-sexing breed, so they should be sexable by down color, but I'm new to having this breed.
I think I know for sure about 4-5 of them, the chick at the top is clearly male, and two of the splits look to be male as well, but not sure about the others. A couple have nice distinct striping but a bit of a head spot so idk?

Thanks for any help you may be able to offer!

Those are tricky! These are the males I'm seeing so far! I could be wrong though

6 week update!
Pretty sure this is how it's turning out for us.
1 cream pullet & 2 cream cockerels (very obvious now that they've got feathers, plus cockerels combs have been reddening over the last week or two)
2 opal cockerels for sure and 2- 3 opal pullets. The barring is very subtle and hard to see even on the males currently. The 2 cockerels are developing larger, slightly reddened combs.
The opal chick on the bottom marked as purple here, we had banded as being suspected to be a cockerel, but is showing good signs of being a pullet, despite that head spot as a chick.

Got their 6 week/off heat updated pics today. They're actually 7 weeks but close enough. Thought it could be helpful for someone in the future. I've dotted them red for probably pullets, blue for definitely cockerels.
