Does the first one have feathers on it's legs?
The second one looks like maybe a White-crested Black Polish
here is a link on polish chicks and at the bottom if you click "polish" you can see the adults http://www.feathersite.com/Poultry/CGP/Polish/BRKPolChix.html
No, the first one doesn't have any feathers on its legs. I have two that look identical, they always are around each other, too.
I'm pretty sure the lady who sold it to me said something about Golden Sebright, but I look a pics, and they don't look like them.
