Genotype of this hen?

[Ylva]

What do you think this hen’s genotype is?
Her father is Fiftyfive Flowery silver, and her mother is either Cream Legbar/Swedish flower hen OR Cream legbar/Rhode Island red.

The 55 Flowery is e+/e+, B/B, S/S and mo/mo.

She is one of the darkest of these chicks, the others are her siblings.

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?

One of her/his brothers are the other chick in the second picture. All of the boys have red combs by now. They are 5,5 weeks old now.

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.

Pullet. I see no male plumage.

Alright, this is weird, it looks like they don’t have any male-specific feathering. This reminds me of the pattern of some hatchery quality salmon faverolle hens, such as these:

They’re basically a really mixed up silver wheaten. However, I’ve never seen one start out looking like a duckwing cockerel.
