How create 55 Flowery Hen

[Gone fishing12]

Hello everyone,
I own a rooster of 55 Flowery Hen and I would like to create a breeding group of this breed. Sadly from the eggs I bought I didn’t get any female. It’s has been hard for me to get the hatching eggs from this breed and it would be nearly impossible to obtain other eggs.
Is there a breed that I can use to cross with this rooster to recreate the breed? I have thought about the Ancona but I’m not sure it will work.

Get gold duckwing brown or silver leghorn hens, keep the female offspring and breed them back full 55 flowery roosters, then keep the mottled females, and breed them back to full 55 flowery rooster.
