Help me sex my little chooks!

[Ol Grey Mare]

Even the first puffed up orpington? She worries me because she fluffs up like a rooster...and she's one of my favorites.

Yes even that one. The feathering on the body is uniform (no dark, glossy patches) and the saddle and hackle feathers are those of a pullet. The comb and wattles of a cockerel would be much more developed at this age as well
