Breed of chick

[Asewall]

I’m not sure what breeds these guys are. They are apparently sexed females but I’m not sure. Any input would help. The yellow with black wings and the black and yellow chick have fuzzy legs. The others don’t. They are about 2 and a half weeks old.

Where were they purchased from?

I'm guessing hoovers/Tsc since the 1st attachment one looks like a Mystic Onyx.
