Silkies are cute. I'm not sure of the breed but I love the look of the speckled ones. My chooks are hybrids, so they just look...like chickens. Our black hen (an Australorpe cross I think) is quite pretty. Some of her feathers have a sort of irridescent green sheen to them, and the ones on her throat are a dark red, blending in with the black.
I think one of the better ones for egg laying is Isa Brown though not sure if they are available everywhere in Australia?
There are some very pretty small ones called Silky or some such which are cute but I do not know much about them...only ever bred ducks and geese as chickens are not as attractive and make far more mess.
