too young.

what is their age? (in weeks) sorry im not good at month and days stuff

Tec27, a fairly accurate guess can be told at about 4 weeks

im sticking with roo and 2 hens

This is the best way to tell the little ones sex.

It won't hurt them to do this.

Pick up the chick after its a few days old by the head.

After it stops kicking in a few seconds, if it holds its legs down its a hen, if it holds its legs up and keeps kicking and clawing its a roo.

Works about 95% or better. If in question wait a day and repeat and see the results.

Heres an interesting article:

Please do not pick up your chicks by their heads.  Very cruel and you could injure them.  Has never proven to be anything other than an old wives tale.  As you see from this article, not only does it not work, but people cant even make up their minds which way would determine a boy or a girl.  Some say legs hanging is a girl, some say legs hanging is a boy.  At any rate, its nothing anyone should be doing.

I once went to a chicken convention years ago and they had lots of baby chicks on display.  I happened to meet the President of the group and asked that very question "how can to tell the boy chicks from the girl chicks" I remember his reply to this day.  He said "It is very easy you get a plait of worms and set it down among the chicks and invariably the boy chicks will eat the girl worms and the girl chicks will eat the boy worms".  I SCRATCHED MY HEAD AND SAID WELL HOW DO YOU TELL THE BOY WORMS FROM THE GIRL WORMS?  HE SAID "HELL IF I KNOW I'M A CHICKEN SPECIALIST NOT A WORM SPECIALIST!
