Wheaten/blue wheaten ameraucanas... gender/colour thoughts?

[PollitosNS]

I have got some straight run ameraucanas a couple of weeks ago - they are approximately 4 weeks old. I could use some thoughts on what they are! Some are more colourful. I'm trying to decide based on the colour of their feathers coming out on their chest... cream vs coloured. Maybe you can take a look at my wheatens and take a guess at gender and blue or not? Total amateur here.

Chick 1: think this is a wheaten roo. Big feet, dark colouring - acts like a roo.

Chick 2: think this one is a blue roo? Colourful like chick 1 but no black. Coloured feathers on chest.

Chick 3: not totally sure? But white/cream chest feathers. Maybe pullet. Maybe wishful thinking?

Chick 4: also not sure. Slightly lighter than chick 3 but Similar to chick 3. Hoping pullet.

Chick 5: think this is a blue pullet. Smaller than the rest and very light - has always been light.

I was told with wheaten the best way to tell is breast feathers. If they get any blue or black feathers in the breast it’s a cockerel. I think they might be a couple weeks too young some don’t seem to have all breast feathers in yet. I think you are right about wheaten vs blue wheaten though. Lucky you I only got 1 blue wheaten from my shipped eggs last year. Hopefully I get a few blue pullets this year.
Here are mine 5 weeks old left pullets right cockerels.

you're definitely right about the first one, probably the second. I'd hold out hope on the rest until we start getting breast feathers.
