Need help identifying gender and breed

[Kelsey081]

here are the little guys, need help identifying the breeds and gender if possible, thanks so much! Three bigger ones are 6 weeks old and the two brown ones are 4 weeks old.

pic 1 looks like a production red. Too early to sex.
pic 2 looks like a buff Orpington (if it has white legs) or buff Plymouth Rock (if it has yellow legs.) Definitely a cockerel.
pic 3. 2 production reds, too young to sex. 2 buffs, 1 pullet, 1 cockerel. 1 white Leghorn or California white. Lean pullet, but it could go both ways.

New Hampshire Red
Buff Orpington Cockerel
Does this bird actually have white legs?
