Help with Sexing Java/ Barred Rock's and some bantams

[Jaygood787]

Hey Ive got some chicks that are around a month old. Some are Bantams and some Java/ Barred Rock. The Rooster was the Java and Mama Hen was the Barred Rock.
I will keep adding pics untill i have added all ten. The bantams are kinda unknown. Execpt the white is a wyandotte.

Could you let me know what you think about sexes.
