Probably all boys... barnyard mix, 10 weeks

[AubreyJo76]

Pic 1- Gannon (coloring and comb say "yes", but my kiddo is thinking no saddle feathers/round neck feathers mean girl)
Pic 2- 2 white chickens... the speckled one on the left is the same as Pic # 4. More plain whitie is in pic #3
Pic #5 -- the one in front, we THINK might've just crowed... so, we brought it in, and not a peep... (I THINK the grey one in back is a girl, due to a lower comb, but she's mean, ha.)
Pic 6- close up of the grey, possible crowing one...

Your only pullet seems to be this one circled in red

The first one could be a late bloomer, or less likely but still possible, a rare hen feathered male. Some roosters just don’t get the pointy feathers, and hen feathering is actually breed standard in Sebright Bantams.

At 10 weeks male specific feathering would just be coming in and might not be apparent yet. I agree with everyone else that you have one pullet and the rest are cockerels
