Help me please figure out sex and breed of our ten 8 week old chicks

[Cluelessshowmom]

I have to get my kids chicks registered for our county fair and I am struggling! All chicks were purchased together from the Bantam selection. I have narrowed some down to Old English (2 Brassy Back and 1 Pile color) I know 2 are Cochin one is Brahma. Help with type and sex is very much appreciated! I have waited as long as I can to get them registered online. Thank you!

1, 2 buff Cochin cockerels

3 buff Brahma pullet

4 splash Old English game. Pullet.

5 red pyle old English game bantam. I believe it is a pullet.

6 Blue OEGB pullet

7 Blue OEGB cockerel

8, 9 black breasted red OEGB cockerels. There's a chance they could be wheaten, but that's less common. Both color patterns are very similar in the males.

10 Another OEGB pullet. Is it pure white or a light blue color? If it is light blue then it's a self blue OEGB.

10 is not pure white, kind of a lavender tint to her. She reminds me of a lighter version of #4
Thank you so much you have helped me out tremendously, I was so tired of attempting to find my answers on Google.

I'm pretty sure 4 is splash because she has some darker blotches of color in her plumage. 10 does not. Her coloring is even. So I think 10 is self blue instead of splash. I am glad I could help.
