Frizzles fighting

[chicken Queen]

Hi all. I have 16 new chickens about 6 weeks old . 3 are frizzles. One is a week older . The 2 younger ones were locked in a beak to beak thing today . The old one seemed aggressive also. I have had chickens before . I know pecking order. This is my first time with Frizzles. Anyone with ideas on these chickens .
