What gender are my 4 week old silkies?

[Ellie Bush]

I have two 4 week old silkies that are very different in behavior, looks, and friendliness. I am almost certain they are opposite genders, but can't tell which is a boy and which is a girl.

The white one has been bigger ever since got her. he/she has long pin feathers and got her comb skin on her beak first. She/he is a lot friendlier and more active than the other one.
the buff one is smaller, had smaller pin feathers when we first got her/him. he/she does not stand too tall and a lot more skittish.
When we first got them we assumed the white on was older, but the buff one has started to grow back feathers before the white one leading us to believe they are different genders. Also, the start of the buffs comb has a yellow tint to it do any of you know what that's about?
Our two silkie chicks are so sweet but are always fighting, trying to see who taller and squawking. They are in a decently sized brooder and have plenty of food and water. We raised the 3 female buff Orpington chicks previously and they had never fought each other. Is it possible they are fighting more because one is a roo? or maybe it has something to do with only having two chicks, I don't know. Any information helps

Thanks, Ellie

Silkies are difficult to sex; these two are no exception. I doubt that anyone will offer a guess. Watch them as they grow and in time... The behavior you describe is normal for both sexes at this age. Mock fights with chicks is quite common.

are silkies more aggressive because my buffs only fought once and that was when we brought them out to the coop

Is either bird injures during these fights? More likely they are having mock battles. Think of it as playing. At the same time figuring out who is dominant and who's the leader. For the most part silkies are docile though I did have one hen that was a terror when she had chicks.

No, its mostly just flapping feathers and seeing whos taller. They sometimes peck but there is never any blood. Thanks for your help!

Too young. Post pics of the comb, crest, and saddle at 12 weeks.

Silkies are one of the most difficult breeds to sex early. Some breeders aren't sure before 4-5 mos. of age. Too young
