Genotype of this hen?

[MysteryChicken]

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?

Pullet. I see no male plumage.

Pullet. I see no male plumage.

Everybody thought she was a cockerel, because of her/his black breast when she was younger. This is her at 4,5 weeks.

By 15 weeks you should tell by sound

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.
