I sure hope they are!!! But what makes you say pullet? Just curious...im completely new to chickens! And if you can tell me what to look for as they grow to determine girl or boy please let me know.
No saddle feathers. And I dont think I see any hackle feathers. When they are growing up, check for saddle, and hackle feathers. Oh I almost forgot! You can tell by pulling out their wings and checking the inner feathers on the wing. If they are pointed, that means rooster/cockerel.
