Mottled houdan hen or rooster?

[CHICKENX2005]

These mottled houdan chicks are 7 weeks old now. Are they hens or roosters?

And just a side note these are some of the nicest chicks I've ever had. Even the younger batch that hasn't been handled very much is just naturally tame and friendly.

I would say female, but crested breeds are not my strong suit.

Crested and bearded breeds such as this can take a long time to tell, so it may take patience with these. I'm guessing they are cockerels based on facial redness and crest shape, but I am not certain by any means.
