What sex do we have for our chicks and help identify one

We have 6 chicks that we got this spring and hoping that we ended up with more hens than roos.  We have 3 EE, 1 Dark Brahma, 1 Barred Rock and 1 unknown.

I have tried to get picture that will hopefully help.  I have some guesses and I am hoping that I am right.  One roo will be ok, since we are getting ready to get rid of the EE roos that we have now(both are getting a little more aggressive). All of these pictures are of the chicks at 7 weeks old. There are a few that were earlier. It is noted above the picture when it is not 7 weeks.

Here is the largest EE chick we have. I am guessing that this one is a Roo.  He likes to be the last one into the coop and seems to be making sure that all of the other chicks are in.

EE1

This next EE I am thinking is a hen. It was very hard to get a good picture of. I will try to get a picture of the comb soon.

EE2

This next EE I am thinking is a Roo.  I am basing this on the comb and the fact that I did see some mahogany colored feathers across the wings. This one also has a crossed beak.

EE3

Here is the Dark Brahma that we have. I am thinking that this is a hen.  This chick is very timid and seems to love to just roost.  It is a very sweet chick and I love the coloring and the feathers on the legs.

Dark Brahma

Here is Barred Rock. At first I was thinking this was a hen,, but now I am think that this is a Roo.  It was hard to get pictures. This one was always on the move.  First picture was taken when 5 1/2 weeks old.

Barred Rock

This one was taken at 7 1/2 weeks.

Here is the last one.  This is our mystery chick.  Solid black with some brown in the wings.  I am thinking that this one is a hen. I am basing that on the fact that the comb is very small.  This chick is 5 weeks old in this picture.

In this picture the chick is 7 weeks old.

I am hoping that the pictures help. I also hope that I am wrong in the number of Roos that we have(want less).  Thanks for any help you can give me.

Thanks!! Have any idea what that Brahma could be crossed with?

Is it possible that my unknown chick is a Black Sex Link? I know that BSL are a BR hen and a RIR rooster. I remember seeing a RIR rooster when we got these chicks.  The place that we got this black chick from has Brahmas, RIR, EE, and Barred Rocks.  All of these birds are free-range, so I am pretty sure that we do have Heinz-57 chicks.

The 3 EE were bought at TSC.

Chick number 1 started crowing this week. Hope the rest of my guesses are right.
