I love to look at my silver-spangled hamburgs. They are beautiful, and so quick and active. They are very shy, but I can deal with that because I have other friendly varieties of chickens that like attention, so I can hold them while I watch the SSH's.
I had two SSH's in my last flock. They were beautiful and very prolific layers. Their eggs were smallish - kind of long and pointy. Be warned, however... if they free range, they were my most tricky layers. We never could find their nests until there were a bunch of eggs in it, and as soon as we emptied it out, they'd find another hiding place to lay. I don't have those girls anymore; they had to go to a new home when we moved.
I have 5 SSH's now, 14 weeks old. One is a cockerel, and he is going to be gorgeous. They are very early maturing birds, so I'm hoping to have eggs from them in the next 4 weeks. I don't remember how early my last girls laid.
