What breed of bantam are these guys???

[Jmerilli]

Hi, I bought a couple bantams from rural king on May 18th making them about 3 weeks old now. I’ve been trying to figure out what breed they are because they bin just said bantams. Can you guys help me out. Like I said Before both are about 3 weeks old and tiny compared to the americanas and cinnamon queen that I got but the grey and white one is particularly small. Like 3/4 the size of the yellow one. What could they be, please help!!! Thanks!!!

White is probably a cochin and the other is probably a silver sebright
