The small white one has fluffy feet, and the small black one has the tuft of hair on her head. I have no clue about breed of them.
The white one is a bantam Cochin. I can't see the other one well enough to really say...it looks like mix breed to me rather than a purebred as it has muffs and a crest and black legs...hopefully someone will recognize it if it is a breed. Lady of McCamley Edited to add: Looked at your location and just remembered the UK and Europe have Araucanas that have tails, crests and muffs. However, the body type looks different, more game-ish to me.... It looks like a Serama body type with a crested Legbar crest or some other crested/tufted and muffed bird...likely an interesting mix breed????
