How soon can you sex a silkie?

[Alexia]

I heard that silkies are very difficult to sex and that they take a long time time to mature. Does anyone know how to sex them and at what age? Thanks

This is my day 1 silkie. Any idea/guess?

I have never owned a silkie, but from my attempts at guessing from pics posted here I'd say after a crow or egg.

It'll take a long time. Sometimes over 5 months. so unless it's an obvious roo early on then it'll be a while.
