Genotype of this hen?

I think so too. I will post updated pictures in a couple of weeks.

Updated pictures of the chick (red ring around the pictures of it) and his siblings, at 8,5 weeks. He still looks more like a pullet except from the black breast. He behave like a pullet as well.

Its a cockerel

Do you think there are any genes who make his comb grow much slower than his siblings? Or is it because he is crested?

It is common to have some cockerels grow their combs bigger and faster than others.

You are asking about his comb, but you had also mentioned that he "acts like" a pullet. Those can both be signs that he is just maturing more slowly than his brothers. So I would say it's a matter of genes or environment controlling the hormone levels that affect comb growth, crowing, mating, etc. It is probably not a comb-specific gene, and probably not because of the crest.

At 9,5 weeks, together with one of his sisters. Still no visible comb. His breast is now spotted with white.
The second picture is of his brothers.

I really love his random mixed-breed colors. It looks like he was colorised by a 1-year-old with no hand coordination.
Is the red caused by the mahogany gene? He is S/s+.

The red could be mahogany, autosomal red, and/or the result of the gold gene

Looks like the Autosomal Red I see often with my birds of Silver.

Here he is, in front of one of his sisters, with their mother in the background. Still looks like a pullet to me, at 15,5 weeks. Most of the pullets are developing a red comb by now. What do you think? Still a cockerel, or do you think he is a pullet after all?
