Hen or rooster

At what age can you start to identify the sex.

 

[Ol Grey Mare]

It depends on the breed -- some breeds are identifiable at hatch, some are easy to tell at just 3-4 weeks and others you must want 6-8 weeks or longer (for silkies it is often months). What breed is the little one you are showing here?

That is a white leghorn about 10-11 days old
