How can I tell the breed

[Mdwinky]

Ok so I went down to my local farm supply store and got 8 chickens, 4 brown leghorns and 4 bantams. How do I tell what breed bantams I have? I've got one with feathers on its feet and it's all black, I've got two that are black and orange in color and the last looks like a sparrow..... Needless to say I'm a bit new at this... Any ideas???

The black one is most likely a black Cochin, the two black and orange are most likely gold Sebrights and the chipmunk one is either an EE or a black breasted red Old English game. If you have pictures it can confirm this or you can look at bantam chicks on feathersite.com to identify them.
