millie fleur d'uccle chick genders

[Happy Hill Farmstead]

My daughter has 6 Millie fleur d'uccle chicks that are between 3 and 4 weeks old. We have never raised these chickens before, we're hoping some experts can tell which are males and which are females? Thanks SO much!!

Chick 1

Chick 2

Chick 3

Chick 4

Chick 5

Chick 6
(this one was rather defient and did not want to be still)

Also, what are their color variations going to look like as adults? When she first wanted them I thought they would all look the same, but they don't some are redder, some are more black and one even looks blonde.

It's still about 3 weeks too early to tell for sure but 5 is definitely a cockerel and 1 is suspect.

Those are the 2 I thought were cockerels too based on combs. 1 is rowdy and likes to strut around and fling his feet at the others so I am fairly certain that it is a he. Can you tell anything based on size of the chick? The blonde chick is way smaller than the others. And 2 is the biggest and always has been; we have nicknamed it "Tubby" because its job is to alert when food is needed or nearly needed.

Any other guesses?
