What age can I post pics of for you guys/gals to help me

[rubyrogue]

I bought a bunch of straight run chicks. They are now four weeks old. Some I know are roosters but what is a good age for me to post pics for help on age and breed?

Six weeks usually. But you can post them now if you'd like to see if we have any guesses

It usually depends on the breed- like if they're leghorns the roo's get huge combs early on!
