Other then being adorable, the frizzled hen is a blue millie, not porcelain. Porcelain is from a lavender gene and she is blue.
But i would like her regardless in my program. ♡
As for mottled hen, if you do, just remember that the chicks will have more blk in them vrs calico/millie. You would either breed the chicks back to their daddy or get another calico/millie rooster to enhance the coloring. But also, watch type. Dont want to loose that while focusing on the colors and patterns.
