Unsexed backyard mixed breed sexing

[LtDanFan]

I have 2 barnyard mixed breed layers and 3 cream legbars left of the eggs i hatched about 8-10 weeks ago. The barnyard mixes are about 1.5-2 weeks older than the legbars. I thought based on initial hatching pattern that the 3 legbars were all pullets, but now, I am more convinced that one is a cockrel and I only have 2 pullets. I am still confused about the mixes, though. They look more pullet to me when i compare them to the legbars but i don’t know how much breed influences at what age and to what extent they will display secondary sexual characteristics.
The first pics are them individually as best as i can get, the rest are combinations of the ones in question (foreground) and ones i am certain of (legbar pullet and cockrel in the background- grey and crested, respectively).

Thoughts??

I don's see any obvious cockerels besides the Cream Legbar in the front. They are an auto-sexing breed and the cockerels are lighter and barred, so it's definitely a he.

Agreed, the lighter colored legbar is for sure 100% a cockerel. He has the distinct male specific color pattern. The other legbar that is pictured is 100% definitely a pullet with female specific coloring. The first bird pictured looks to have female specific coloring as well. The black one has a small, pale comb and wattles, she looks like a pullet to me.

I figured out that the legbar in the foreground was a cockrel after he developed his grey pattern and the other 2 developed their rose breasts, but unfortunately, from that clutch i lost 3 to tragedy and don’t have pictures of the survivors to go back and look closer at the initial hatching patterns, other than the obvious male was one of the ones killed. From what i recall of the survivors, I thought they all looked chipmunk striped and pullet, but clearly one of those was less obviously not.
I was using him to compare the two BYM’s that survived and was hoping that they looked more pullet than cockrel. Given their origins. I was given those eggs by a friend and shortly after they hatched, the hen that laid these eggs fell victim to a predator. Then we had a fire that took the other 4 of their clutch.

I just did the math and the barnyard mixes are right at 10 weeks, CCL’s are about 8. Would I expect to see signs of “manliness” (rooster-liness? Haha) at this age in the BYM’s? I was presuming that because the CCL is younger, and his comb is already more prominent and redder than the BYM’s that they were pullets.
