What breed are these?

[Wyandottes7]

The black and white ones may be Anconas, or poorly colored Speckled Sussex. The red bird is likely a production red or Rhode Island Red.

Is it likely the if the black and white ones are either speckled sussex or anconas that the hens could develop spurs and are they available as bantams?

some hens develop spurs, some don't. it is more likley that they won't but if you are trying to sex them never go by spurs. I am not sure if they come in bantams or not
