Wendy, everything about chickens, not literally everything, LOL! Seriously, I'm happy to answer what I can and if I can't, I'll say so. And I can't tell about the SSH's in the picture, sorry. No experience with that breed at all, but look up how that breed was made and you may find that there was a single-combed breed used in its development. That's why Wyandottes sometimes pop up with a single comb, because of their Cochin ancestry.
