Is the brown chick a boy?

[emat]

All the white ones look like pullets to me. The light brown and white looks like a roo. I can’t tell for the mostly brown guy. I’m leaning toward roo. All are mixes

the white with orange speckles is a cockerel, your only one so far.

Age? What makes you think the mostly brown one is male?

Right now nothing is screaming male to me. Although if they're under 6 weeks there really isn't anything solid to base our guesses on. None of them have male specific dimorphic coloration (or female specific for that matter). All of them have equally pale combs. Unless they're over 9-12 weeks old they aren't old enough for pointed male saddle or hackle feathers to have grown in yet.
