Fairly new and want to ID chicken breed

[TheOddOneOut]

I have had my chickens about 4 months or so and want to ID one of them. I bought the chickens as young, but not chicks. I'm posting a pic of one of them. Very colorful, but shy, standoffish, etc. I have 3 RIR hens and one big white Delaware rooster to go with this colorful bird.
What breed is she and how to I "make" more chicks like her?

Mixed breed male.

He's a mixed breed. His color looks like black breasted red or partridge if that helps you find other breeds with similar appearance
