Sorry, but every single chicken in all your pictures is a rooster. I'd advise to get rid of them and start with a nice flock of hens. Keeping that many roosters might be okay if you have no hens at all, they have nothing to fight over and just posture some with each other. You'd likely have to get a few dozen hens to keep all those hormonal young roosters satisfied, and that' a lot of birds to jump into. Also, they're fine and sweet now, but you have kids and roosters and kids don't always mix, especially once those hormones start flowing.
