Curious about chicks breed

[McChooky]

We just got some OEs from Ideal and they say theirs are a mix of an EE and either a Welsummer or a Barnevelder. Maybe yours have Welsummer or Barnevelder in them and that’s what’s bringing the different colors!

Barnevelders are dark(black and red)

That one’s a rooster. The hens have more brown, no?

I know I can't tell what gender our chicks are yet - but I'm curious if anyone has any thoughts on their breed? We bought 4 at Tractor Supply that were marked as pullet Olive Eggers. I know this doesn't mean much as far as breed or gender since it was TS. We hatched some eggs 3 mo back and they were ALL roos that we had to rehome, so my daughter begged for a few chicks in hopes of some hens. I'm hoping, too

But I'm mostly asking about breed because they look nothing like I predicted. I thought they'd be black and look like marans bc I've read most olive eggers are half copper maran. These look much more like Easter eggers to me - but I'm surprised by the Auburn/reddish feathering they're all developing on their breast area?

Any thoughts? I'm new to OE. These pics are all 1 chick bc they all look pretty similar. This chick is about 3.5 weeks old.

Any update? Pullets? Have they started laying yet?
