The 2 are a Goldlaced type Polish, they have the big Polish curvy nostrils. Their topknots will come in better, but probably not as nice as if they had the big ball on top now, but they will be pretty non the less. The Black could be a Black Polish, or Crev, I'll have to double check mines legs, I thought they'd be all grey w/ no pink but it's been awhile...... Hatchery Crevs normally don't have the greatest topknot till they start getting older
