Silver Ameraucana.
A long-tailed, crested, bearded, muffed blue egg layer in silver Duckwing, golden Duckwing, blue, black, splash and lavender. Maybe spangled and laced.
You mean Legbars? Lol
No beard or muff, but you could mutt them up with crossing to Ameraucanas if you wanted. Cream looks like silver crele Duckwing, there's also golden crele, white, blue crele, lavender crele, and someone is working on pumpkin. The only limitation in what colors are allowed is the pattern must be autosexing.
