What is this little guy?

I'm still not sure if it's a girl or boy, but that red that just appeared recently on the wings makes me think boy. I was sure it was a girl up until that came in.

My son is 5, btw, to get an idea of its size. I have 2 this size that I'm sure are the same breed, 2 different colors. The other I think is a black breasted red.

 

Yeah, but what breed is it?

Here's the other cockerel that's the same size, I think same breed, different color.



Are they Dutch or OEGB? They're the smallest of all of my bantams. They're about the same size as my Polish bantam, but he's 2 weeks younger. They are smaller than my silkies, who are also 2 weeks younger that the ones in question.
