Seemingly strange coloration on olive egger chicks

[Rex Montana]

I have some olive egger chickens that I have raised from chicks. I purchased them from a supply store and they are a cross of Welsummer and Cream Legbar. We decided that we wanted some more so we let them hatch some eggs. From what I’ve read, the cream Legbar is an auto sexing breed, and some say that the Welsummer is also. So I figured there would be traits of both that I could look for to determine the sex. There were a couple chicks that were easily identified as roosters according to the cream Legbar half, they looked exactly like the cream Legbar chick pictures for a rooster. The Welsummer Seems a bit more difficult to determine. The strange part of it though, is some of the chicks that hatched look nothing like either of the breeds. Both aforementioned breeds have lots of dark coloration, and 3 of them came out with white stripes where there should be dark brown or black stripes...kinda like looking at a photo negative. Is this some gene that is coming out from a Welsummer or Legbar ancestor? I would’ve thought that they would have come out looking like the parents.
First pic...daddy

3. Chick that I assume is a rooster(cream Legbar coloration)
4. This is what the olive eggers are supposed to look like?

The cream legbar hen is barred, so any chicks produced with head spots will be male, & I see two.
Solid Male over Barred Female = Barred Males, & solid Females.

Chick #1, is Male
Chick #3, is Male
Chick #2, is female

So the dark stripes one is also a male? Any thoughts on the little yellow one? How it came out that color? Whether it’s a male or female, I’m dying of curiosity on how it will look when it feathers out

The chipmunk one is female.
The yellow one is Male I see a white headspot on him.

Ok thanks, I have 2 of the yellow/white ones and I wasn’t sure if the wing feather sexing worked on these chicks....I’ve got a few that have the same father, but a Buff Orpington mother...those ones are the color of the buffs, and a few have dark spots on their heads and some had faint stripes...curious to see what they will look like also

Have pictures of the ones mothered by the Orpington hen?

Here’s one of the new chicks, only 2 days old...got a faint dark spot on the head, some of the wing feathers are already coming in and they’re grey. I’ll try to get a pic posted of the one that’s about a week old...that one started feathering fast. Had a couple dark spots on its head and the wing feathers are grey colored. Got the last egg from the buff mama hatching probably today...it pipped last night

A dark spot/stripe is common with Wheaten based, or pure Wheaten birds.
Since it's part Orpington I might be able to wing feather sex it.

first one is 2 days and 2nd one is 3 days...2nd one has 2 distinct lengths of feathers but it’s kinda hard to tell in the pic

Number 2 is a cockerel.
Number 1 looks to be a pullet.
