Gender of midnight marans, silkies, polish, orpingtons

[LaurEliz]

I got these chicks last month and was wondering if anyone has any guesses on their genders.

1.) Midnight marans

#2 Lavender Orpington

#3 Lavender Orpington

#4 Silkie

#5 Polish

#6 Buff orpington

#7 Silkie

I realize these might not be the best photographs either, but any guesses are welcome.
Here are a few more pictures of them.

I'm guessing #3 is a cockerel.
The others are either pullets, or too young for me to tell.

3rd looks suspicious. I’ll go with cockerel.

You’ll have to wait a couple of weeks for the Polish. And you won’t have much luck on the Silkies until they’re at least 10 weeks old.

1, 2, 6 are looking like pullet so far though.
