Silkie with straight comb? Help sexing!

[BantamAshley]

This is a 6 week old silkie that I suspect is a rooster. Included is a current picture of its comb developement. Is there any chance he may still be a she?
Thank you!

A bit young yet.

At 6 weeks old the comb is still developing. Silkies are very hard to sex, one of the hardest. Around 4 months you should see streamer feathers going back on the top of the head

Please post pics of the whole body, crest, and comb with crest pulled back at 12 weeks.
Hatchery quality silkies have single combs sometimes.
