Barred Rocks - 3.5 weeks

[Coldd]

We have four barred rocks and two of the four's feathers are coming in mostly white, with black bars. One is much darker than the others, another is your typical looking BR, while two have some feathers coming in that are mostly white with little bits of black barring (Mostly around the neck and head).

These are 3-3.5 weeks old. What do you think? Male or female? I know it's early, but I seem to be seeing conflicting things via google about sexing the chicks. The ones in the back are Jersey Giants.

Thanks!

Those might be Plymouth Rocks, but other than the breed, I am not able to tell which gender it is.

The chick in the first picture is not a barred rock. Could be a roo, its waddles are pretty red for that age, but too young to tell.
