Did the Faverolles parent have the extra toes?non of the Faverolles mixes off my orp boy have had extra toes- They've had all the other features though
If both parents have 4 toes per foot, all the chicks should too.
If at least one parent has 5 toes, and there are more than a few chicks, I would expect at least some chicks to have extra toes.
