10 Week Old Plymouth Rock--Hen or Rooster?

[Joanna6]

Hello, Can someone help me determine the sex of this 10 week old Plymouth Rock?

You can see the development difference in your third photo. The bird in question is a rooster. The others are pullets. The comb difference is signficant, and usually shows up in BRs at 10 weeks.

Hmmm....bird to left of bird with arrow may also be a rooster.

The other 2 look like pullets.
