Maybe a rooster?

[Lumikko]

I have three buff orpingtons who are just under 3 weeks old. One of them has always been bigger than the others and while I'm gathering it can be difficult to tell rooster versus pullet at this age, what do you think? Baby rooster?

One of the others, just because she's cute

The top one, possibly a cockerel. His little comb is awfully large and pink.
Little one below is showing signs of being a pullet.

I would think that it’s a cockerel, as I remember at this age, my rooster looked quite similar.

It definitely would be a male if it has a red comb at this age... but I would get another opinion if I were you, because this is only a guess... either way, both are super cute!

Yes, cockerel.

FYI.....semantics, maybe, but can be important communication terms when discussing chicken behavior.
Female chickens are called pullets until one year of age, then they are called hens.
Male chickens are called cockerels until one year of age, then they are called cocks(or cockbirds or roosters).
Age in weeks or months is always a good thing to note.

Cute little cockerel.

I appreciate the correction - thank you!
