Lavender orpington gender help?

[Forestdweller5651]

Just wondering if anyone can help me out with the gender ID of these chicks. They are around 10 or 11 weeks old or so.

Looking for just the lavenders, the Wyandotte in the front is a little roo.

For 10-11 weeks, combs are small with little color and little wattle growth or color, so I would think female. However, I've not had Orpingtons until this year with my 7 week old buffs, so my Orp experience is limited.

Those are pullets!

Those definitely look like Pullets to me also, Unfortunately I'm pretty sure mine is ALL BOY, super sweet and docile but...well, I will attach a pic so you see the difference.. He's 4 weeks
