Going crazy figuring out gender.

[CochinLover]

First I thought they were Tolouse but they are definitely mixed. Some have white flight feathers 2 don't. They all raise their heads high when talking, all put their necks down when excited about food time or clean pool. All are gentle except one is getting feisty. They are getting their big boy/grils voices. For sure one honks but they can be pretty quiet. So im at a total loss. All of them have white splotches on their chests and necks. One has a ring around it's neck. Help

Vent sexing is the best way when they’re within a week old but that’s well past the point now, however they’re still too young to determine gender based on behavior and physical differences so they’re at the in between age when it’s hard to say.

Usually mature males will have a slightly longer neck in proportion to their bodies than females, and mature females tend to be more squat.
Ganders tend to like to get in between whoever they’re bonded with and intruders or non bonded flock members, so if for example you were to approach the gander will often appproach you and stand between you and his girl. Things get more complicated however with flock dynamics. Less dominant males will stay back, ganders can also be protective of other ganders. Some girls can also be more feisty than others.
