Mystery blue chick and others

[Appaloosa Hill Farm]

Alrighty, I have a couple questions for a few different chicks. First up:


Here's my 5 week old EE. I SWEAR I heard "him" crow. Am I right? Is my "garanteed pullet" an roo?

Next is my 2-3 week old bantam Cochin. What color might this little gal/guy be? Also, with the pic of its face, anyone care to guess the gender might be?

Last but not least is the blue-dyed bantam (I think it's a bantam--it's 1/2 the size of the pink-dyed EE of the same age that my daughter received as a gift.) that my son received as an Easter gift from a relative. I have no clue as to its breed or sex. It has some odd-shaped feathers coming in on its wings. Well, odd to me as I'm fairly new to chickens!

Thanks for any insight y'all may be able to share with me!!!!

First one could be a roo.

Too early for me to tell anything with the other two.

Do the feathers on the blue chick look odd to anyone else? I've not had one feather in the way this one is...

The comb on the blue chick is pretty pink for a 5 week old - could be a cockerel.
