Sebright males

[Jae]

I have 4 sebrights. 2 have combs and 2 have nothing up there. They are only 7 weeks. Will hens have a comb?
One with a comb is defiantly a rooster. He crows and is a butt head.
Just curious how I will know about the other 3. I suspect two without combs are hens.

Hens have combs that develop later and are considerably smaller than those of the roosters.
