Who is who??? FBCM Roo and 5 breeds of hens

Please help us figure out who is who. We know the roo is a FBCM. We bred him with BR, BO, EE, WS, and FBCM. We know 8 are EEx's but we do not see 8 with puffy cheeks. We know 16 are either BOx or BRx - I did research prior and know the FBCM roo x BR hen = sex link. It looks like we have 5 males, but two more have white dots on their heads and we think they are EEx. Photos below.
SO .... which ones are WSx and which are BOx? And will the EEx all have puffy cheeks? And can there be variations within the cross? I know the EEx are different, I assume the BRx will be consistent, but what about the BOx and WSx? We have some with stripes that could be EE or WS. Some that are a cinnamon or dark chocolate color. We have some that look like straight BO. (but percentage wise there should be several more BRx than BOx based on egg color alone ... 5 BR hens and only 1 BO).
Anyway - see photos. The first one has all the non-black chicks, followed by a few close ups of the same, and then black ones. Thank you for any help. If you need better pictures let me know. We are pretty confident with picking out the FBCMs and the BRs.


Cinnamon/chocolate example


Stipe example ... the second photo we think the one on the right is an EEx. The third photo is another angle.






And here are the two black ones with white dots on their heads that we assume are EEx

What is WS?

I think you might have to wait at least until they're feathered to have good guesses at Mommas. The Marans and the Orps both have white skin, which is usually dominant. You can probably tell the EE mixes by a pea comb, if all the hens were pea combed. That's a dominant or partially dominant characteristic. Otherwise, the black from the Marans (if he's pure for black) can obscure a lot of other colors. And just to mix things up a bit, with all the non-black chicks you got from those breeds of mommas, I'm thinking your rooster may be harboring some recessive genes for Wheaten. I'd expect a lot more black chicks from him if he were pure for black.

Sorry - WS Welsummer. I'm learning ... thank you for responding
We now have the hens separate so we know we are not collecting any BO or Welsummer eggs. That should help a little. Also, we'll go even further and make little compartments in the hatcher for each kind. I wish we would have thought of that sooner.
Is there a link you can point me to that teaches about traits / genetics?
Thanks again.

Also - we hatched out 51 chicks. Most of them are black & white. We can see some copper (a little mixed in with the black on the head and upper back area) on the FBCM that look just like our males when they were new chicks.

Not a very good picture but here they are ... hatched between late Wednesday night and early this morning (a little more than 24hrs apart)
