Gender? Maran Chicks.

[Butt_Nugget_Hut092]

Hi,
I know it's a little early to tell for sure these guys gender. But I keep reading that marans are sex link or auto sexing breeds but no information on what specifically to look for.
So these guys are estimated around 4 weeks old. Came from tractor supply and rural king. Mostly cuckoo marans I believe.

Chick Number 1 Cuckoo Maran

Chick Number 2 Cuckoo Maran

Chick Number 3 Cuckoo Maran _ Tractor Supply (This one refuses to sit still long enough for a photo.)

Chick Number 4 Midnight Majesty Maran _ Rural King (Bad photo, also will not sit still)

I'm leaning cockerel for #3, since I see some wattles popping out already.
