Ancona

Thanks for the respond.
I try to understand what causes these dark spots on the yellow legs.
Some say it's normal for mottled colorations (mo/mo), others say it's due to a variant of the dermal inhibitor (id^a/id^a * id^a/-) a sex-linked mutation only on Anconas !?
For confirmation on this I am counting on the expertise of Crestillo.

In contrast to what I readed before the Black white mottled Ancona's carry Melantic ! Can you confirm they have a green shine on the black feathers ?
Did you ever did crosses with Exchequers ? If yes what are your experiences ?
