I need help with rooster vs hens please and thank you!

[Taniahdh]

I am new to poultry farming but my family dove right in with 5 ducks, 6 turkeys and 19 chickens, all are about 10 weeks old. Some of the roosters have started to crow and while we can have chickens in our neighborhood, we cannot have noisy birds. I’m trying to sex my birds but don’t know how to know for sure which ones will stay and which ones will go as not all the roosters are crowing yet. Any advice would be much appreciated. I also don’t necessarily know breed so if you have any insight on that, please let me know. I can post more pictures, these are just a few I’m most curious about. Some birds’ gender are quite obvious while others are not. The ameraucanas and olive eggers are really hard to see. Many thanks!

Here’s another one I’d like to sex.

The first bird, the brown one with the large crest, is female (and lovely!).
In the third picture, from left, 1, 3 and 4 are male. I can't tell with the others as they're facing away.
Picture 4, the little black bird is a pullet and the blue one next to her is a cockerel.
Picture 5, the two brown birds in the pen behind are both pullets. The two orange ones furthest away in the front pen are male; can't tell with the one in front. The blue facing right is male. The black one beside him is female. The little silver laced wyandotte in the bottom right corner appears to be female, with a male gold laced wyandotte beside her.
The Splash bird in picture 6 appears to be a pullet.

Ideally, pictures of each bird alone, like the picture of the Splash in #6, would be better to help sex these for you. It looks like you have a nice flock, but you're going to have to thin down your cockerel population soon; you don't want the pullets getting hurt by too many rambunctious boys.

Many thanks for your wisdom! Do you think the buff in picture 2 is a male?

 

[Sneebsey]

I believe I've seen picture 2 as #3 since the first was posted twice; I see three boys there, including the red one.
