What exactly are these?

[Kecobb]

I am new to chickens (well, been a long time since I've had any). I have some questions...

1) is the little Red a bantam? She's the same age (no more than a couple days younger) but about half the size of the other 2 Reds.

2) what is this cockerel? He was supposed to be sapphire gem but I doubt he is

3) is this blue/Grey pullet a SG or...?

4) how do I know if these darker barred pullets are marans or what?

Pictures to correspond with the questions. All are about 6 weeks old. Thanks in advance!

1) No, she appears to just be a bit runty.

2) Cuckoo Marans cockerel.

3) Likely. What color are the soles of her feet?

4) I see one CM and one BR. Look at their skin color on shanks and feet. CM will have white skin, BR will have yellow.

X2. Can't really add anything else.
