When I got the chicks, I was told that they were Orpingtons. Except the black one, he wasn;t sure what it was. I think it's going to be something ornamental because of the chubby cheeks and chin. The grown ones were given to me on Friday, and I have no idea what they are. So, what do I have?
They are from a local chicken farm. We drove there, only about 10 mins from where we live. There were chickens everywhere. The man hatches chickens to sell. He has a sign and a small cage with chicks at the gas station. We called and went to pick them up. The batch we picked from was probably about 50 chicks under a large lamp.
you can't tell from the picture above, but the rooster has purple and green highlights on the side feathers. Here are some better pics where you can see the coloring better.
Your hen is a game bird. Scrappy little things, they're known for being great foragers and mothers. Usually not the friendliest bird in your coop, but won't get picked on by larger birds, either, unless she's broody.
Your barred rooster is probably a black sex link, meaning his momma was a barred rock and his daddy was non-barred. He may be hatchery quality pure barred rock, but they're usually a lot lighter. He's pretty dark overall and his barring is pretty messy, not nice and crisp, making me think he's a mix.
Your yellow chicks aren't buff orps, they're feathering in more like some red --production/new hampshire/etc. Could also be red sex links. And I can't see your dark bird, but the puffy cheeks tells me it may be an easter egger. Post more pics of the babies in 4 weeks or so, we'll be able to give you better info then.
