The breed certainly is a challenge not only because of color but also because of the extreme type, beard, foot feathering, and fifth toe placement. Plus understanding the intereaction between color selection in males and females. Some argue that to show successfully there must be a cockerel line and a pullet line. Others including myself disagree. Very interesting subject faverolles breeding. I could go one all day. Thanks for the comments.
I raised them in the early 80's. Yes, they are difficult, Back then there were some good ones out here in the west. I see some good ones now here but only occasionally. I believe most breeds/varieties can be single mated, but it is harder to do than doing the double mating.
