I hadn't heard of Polish until today (granted, I'm really new to chickens - we got our first about two weeks ago), but I've seen two threads about them here today and I'm totally in love.
I have an insane polish roo, hes my avatar, so Im thinking the blue is a roo because of his crest feathers growing up, out then down, like mine did, and I think the other is a hen. Ive always seen the hens with real bushy head feathers..
