To be honest
I really am not sure about whether it's a hen or rooster,
Silkies are one of those breeds that are hard to tell
If there male or female untill atleast 4 months
Maybe someone else might know
Goodluck
I know I said befour I am not sure what it is.
The more I look at the picture I think rooster.
The Silkie you have
Looks like it has a roosters body shape
So now I think it's a rooster
Goodluck
