Sent you a DM with the links--for the record, I'm happy to send them to anyone else as well, just send me a message!

I love to see silkied Cochins gaining interest!!
Yes, I think Showgirls are considered a type of Silkie. If you find any silkied NNs without the Silkie traits like Showgirls have, I'd love to hear about them, too! I just love silkied feathering.
Ah, you mentioned that about Sandhill on another thread! I'll keep them in mind for the future. I've got to get a secure setup built for Ameraucanas before I can commit to getting any more than a hand full for my mixed flock. I really, really want to preserve them alongside my Cochins, though, as they've became so rare I was getting worried they may just disappear entirely!
