The second chick looks like a Gold Dutch bantam, I'm not sure about the first. Looks like some kind of Old English game.
Maybe. What did the manager tell you the breeds were? http://www.feathersite.com/Poultry/CGD/Dutch/BRKDutch.html Chick pictures are at the bottom of the page.
Wow, those look a lot like light brown leghorns... although I’m not sure what the golden bantam looks like as a chick-all mine are adults as I bought them
They look like oegb to me. I would guess one of the duckwing or more likely a bbr. The too appears to be a male and the bottom I'm guessing is female but could still surprise you by being a boy. I have never gotten nor know of anyone that has gotten Dutch bantams from tractor supply, at least not around me.
