I'm in Michigan.
For availability, it's too late in the season, but the silkies I do have are:
Largefowl Whites
Bantam Partridge, Blue Partridge, & a white
Not gonna be available for breeding: Black, & 4 whites. These boys are getting culled.
You can cheat by using Mille Fleur D'uccles. They're Gold, Columbian Mottled.
You can experiment using Buff, Black, or Dominant white Silkies, & breeding them to the D'uccles.
Here's a Generation 1, Porcelain D'uccle X White Silkie hen. My whites are split for lavender.
Just remember mottling...
