Time to Play "Sex That Chick!!"

[Humhill]

Each of these lovely contestants will be 5 weeks old this Saturday. They're supposed to be all pullets.

Contestant #1:
EE - was yellow when I got her/him. Think mature color will be white?

Contestant #2:
Also an EE - was yellow with chimpmunk stripes when born. What color is this?

Contestant #3:
SLW - This one's comb seems to be growing more than some of the others.

How can you tell? What do you look for? Any idea what color the second one may be?
