4 wk old Salmon Faverolles sexing

[leia_and_friends]

This chicks, called Favi (no prizes for guessing why) and also, (being a little on the plump side), sometimes Fatty, is my only Faverolles put of a batch of 6 chicks. She/he is 4wks old today - I really hope it will turn out a pullet as it is one of my favourites. She/he had quite fast feathering, (tail feathers coming through one of the first), and generally light coloured except today I noticed some darker feathers (greyish black) coming through just above the base of the wing.
The breast feathers that have come through are mainly light (not much salmonish) but there are a few that are darker in the unopened shaft. Also his/her comb is very yellow... very probably my overactive imagination but is there a teeny weeny bit of reddish colour?
Thanks in advance to anyone who can help.

( The last two pics are the breast feathers)

Black typically indicates male. Time will tell, but here is an image from the web of male and female SF:
