ITA w/polarbear on the pics for afreeman0405.
The blue gal is the only one that gave me pause because I've seen a few males hide past 9 weeks but there is no red on the wing/back and the comb doesn't appear to be growing so I'll say most likely female.
ALL of them but the blue one? gah! I hope not. I am waiting until eggs or crowing to figure out what to do with them.
