Breed/Gender of mystery TCS chicks

[bhill]

Hi-I'm new to backyard chickens and am very excited to grow my flock! Last month I purchased 2 RIR and 2 what I was told were SS from TSC. I now know these two are not SS, but I still can't figure out what they are. Additionally, the one on the right is about half the size of all other chicks (all now 4-5 weeks old). It still does not have a tail and looks like it is trying to develop a comb but it is flat. Any guesses at gender would be great too!

Maybe Dominique one looks like it may have a rose comb.

A Barred Rock and a Dominique
The one in the back, the possible Dom appears to have a rose comb, like @Littleblackstar said. Closer pictures of it would help confirm

One in front looks like a dominique, but the one in the back looks like barred rock. (Hence the barred feather pattern.)

The one in the front is a Cuckoo Marans, back is a Dominique. Based on their coloring they should both be pullets.

Barred Rock and Dominique. Look like pullets.
