Are my chicks old enough to sex?

[Zenzilicious]

Hello!

I have 5 Buff Orpingtons @ 5 weeks old,
3 Silkie/??? Mixes @ 5 weeks
1 Silkie @ 8/9 weeks
1 Silkie/Mille De Fleur Mix @ 8/9 weeks

If they're old enough, I can post pictures.

Thanks!

You can post pictures and try. Generally we say 5 weeks is the starting point, but Silkies usually take longer.
