After asking around it seems that a Legbar cockeral over an Ancona hen would be the best way yo start. Then it would be a matter of crossing the off spring for a couple of generations to fix the recessive mottled gene and the chipmunk markings on the chicks.
I like the appearance of this very rare breed but I can,t seem to source any. So I wondered would it be possible to create my own line by adding the mottled gene to Cream Legbars using my Anconas.Any idea how best to go about it ,how many generations would it take
Thanks
