You keep dropping pearls of wisdom for me donrae, I really appreciate it. I'm not sure if you saw this, I wrote in an earlier post:
"The seller currently sells Light Sussex, Rhode Island Red and Barred Plymouth Rock. They will soon be selling more varieties, so I assume these could also be possible, they are; Vorwerk, Silver-Laced Wyandotte, Welsummer, Barnevelder, Black Rock and Ayam Cemani."
They have started selling all of the above breeds since I started this thread. Now I know! Barred rock x silver laced Wyandotte. My chick must come from a barred rock hen and a Wyandotte rooster as the eggs where all the same colour and it would have been collected from a barred rock pen.
Thanks again!
