Reddish chicks will be some type of Red birds. Rhode Island, production, cherry eggers, sex links, along those lines.
Black with a white spot on the head means barred Rock, or possibly cuckoo Marans. Yellow skin and straight comb is Rock. White/pink skin and straight comb is Marans. Yellow skin and rose comb is Dominique, which are kind of rare at a feed store, around here anyway. Straight comb and yellow skin and feathered legs would be a barred Cochin, also pretty rare around here unless it's in the bantam bin.
Black with white underbelly and no spot on the head is probably an Australorp. Black with a solid head and underbelly is probably a black sex link pullet.
Chipmunks can be a lot of different breeds. It's the base color for partridge, black breasted red, pretty much all the brown/gold colors. If they have greenish/dark legs, pea combs (just a wider spot vs the little sawtooth of a straight comb) and a beard, they're Easter eggers.
