There are five or six boys (we got a random free chick which is probably a cock) and the rest are girls. Although right now they're all just small and meepy and fluffy and somewhat dense; male or female doesn't seem to make a difference and you sure as hell can't tell.
When they're bigger they'll be: Buff and Golden Polish, Black Minorca, Blue Andalusian, Light Brahmas, Silver Leghorn, two Phoenix cockerels (which will have STUPIDLY long tail feathers) and a Sumatras cockerel. All of this lot have very pretty feathers and some of them have mad feather-puffs on their heads.
For anyone interested, this is what they'll all look like when they're older...
