Sexing by Comb - 5 weeks old

[ChickenAJ]

Hi!
We have twelve chicks. We know one is definitely a rooster, but trying to understand if there are any others.

Can someone help me figure out HOW to tell a rooster among the different styles of combs?

Here is a picture of my Splash Laced Red Wyandotte. 5 weeks old. Rose comb? How can you tell if they are boy or girl?

Wyandotte cockerels show around 6 to 10 weeks, rosecomb. The single comb version shows at 4 to 5 weeks.

What do the cockerels “show” around 6-10 weeks? What signs do you see?

Redder and growth in comb.

Look like it can go eather way. Boys tend to get red combs and grow feathers slower. They tend to be heavy and bones thicker. Mostly look for the right red that shows up. When neck feathers come in look to see if they are very long and thin or wide and short.
These are hens for reference
