Three Random Babies. Need help with sex and breed

[Josephseda12]

Good Morning Everyone!
I'm fairly new here. Just looking to get some help sexing and determining the breeds of my babies. The all black one is about 6 months old and has feathered legs. The other two are 4 months old.

The brown one could be a game breed, though I’m not certain. The other two are mixes. The black and white is a cockerel and the black one is a pullet.

Thank you so much. Glad that I only have one cockerel
