Buff Orpington, Buff Rock, or???

[MIchickenlady]

Hello!!
I got my sexed chicks from Tractor Supply in July 2017.
The girls are 20 weeks old now, and I'm wondering why their combs are so different?
Two girls have red, more developed combs, and two have more pale, small combs.
I've already been advised here on BYC that one girl is probably Buff Rock due to her yellow beak/legs. She is one of the small combs. The other small comb girl has white legs but a body more like the Buff Rock.
Any thoughts what these girls might be?
I thought i was getting all B.O.'s....but I've grown attached to all of them anyway

Can we see pics of the two with the larger combs from the side, whole body? At this age, they could either be point of lay pullets, or young cockerels...

I have two buff Orpington sisters and their combs are different. One is a larger comb than the other

Birds mature at different rates of speed. Two of your pullets are maturing more rapidly than the other two. They are Buff Orpingtons.

Bigger combs are just closer to laying eggs although there is variability in comb size as well, particularly in hatchery stock.

And as for the yellow legs, if they otherwise look like buff Orpingtons, I'd chalk that up to the hatchery not selecting for proper traits. They focus more on production and let them be "breed representative" rather than show quality.

Ok, I tried getting a few pics of these girls, but the sun is out so they're very busy lol
The one I'm confused the most about is Sassy. Her beak had been getting a little more yellow like Sunny's-the Buff Rock who has yellow beak & legs.
Sassy has pale legs though...whaddya think?? The first 2 pis are Sassy, for comparison, the 3rd pic is Red & Tiny, both with more developed wattles, red big combs.
