Welcome to BYC! Please make yourself at home and we are here to help. I'm not good with breeds. You should post in our breed and gender area. https://www.backyardchickens.com/f/15/what-breed-or-gender-is-this He's very pretty!
Welcome to BYC. Glad you decided to join our flock. My wife and I were both raised in the great state of Texas. Your rooster is a Black Sex Link rooster. Your black hen to the left looks like a Black Australorp (I can't see her leg color to be certain), and your other hen on the right is a Red Sex Link. Please feel free to ask any other questions you may have. We are here to help in any way we can. Good luck with your flock.
If I had to guess I'd say a Rhode Island Red but, don't quote me it's just a wild guess. Put her photo in "what breed or gender is this." I'm sure you get some fast results.
She's a Production Red hen. She likely won't quite match the lay rate of your Red Sex Link hen, but she should still be an excellent layer. Your Black Australorp hen will be an excellent layer as well. You should get lots of nice, large, brown eggs from your girls.
