For the 3rd bird....
At 10 weeks, I'm not worried at the slight rose in the comb. That is a rosecomb, by the way, not a pea comb. At least it looks like it on close up zoom (from photo 3).
A pea comb will be a line of 3 pea rows, think ::: often with the middle pea row a bit higher than the border pea rows. Some believe that 3 distinct pea rows means rooster while a main middle pea row, with very small hedge rows, means female, however there are enough exceptions to prevent that from being a solid determination.
At the juvenile stage, a rose comb looks like an upside down U like a horseshoe with the luck running down the beak. Rose combs tend to flush with activity. Male rose combs get quite fleshy, filling in the indent, earlier, and redder. Female rose combs will stay flat, indented, longer, until point of lay, and flush pink with activity but return to paler colors upon rest.
So I think you have a pullet. Her coloring is even. No red bars on wings. Her comb, while to my photo eye is rose comb, is small and only a bit rosy.
She however would not be an Easter Egger most likely. What she is could be a factory "oops" or possibly a game type. If you breed a pea combed Easter Egger (originally derived from Ameraucanas, which were very expensive birds originally, thus watered down through mixing with layers to produce EEs), to a rose comb bird, you get a cushion comb, which she doesn't have. Thus I doubt she has any EE in her, but it is possible if the EE line was very sloppy and had enough comb variations. Be aware that if you desire blue-green eggs, the further away you get from Ameraucana genetics, unless lines are carefully controlled following the blue shell gene, the less likely the blue shell gene passed. The pea comb is linked with the blue shell gene, so if Ameraucana is in the past, and the bird has a pea comb, it is greater likelihood that the blue shell gene passed to, in EE's.
It is quite possible she is a Game mix, possibly Old English Game, especially if she is just a bit smaller and lighter than the others. Though she doesn't have a true game profile, usually their wing line dips below their body, she does appear more "hawkish" than the typical layer. Games have green legs as well as many EEs.
If you aren't that concerned with egg color, or breeding forward, she will be a jaunty little lady that you will enjoy for her beauty and charm.
