I forgot to mention a detail when I bred my Sex Linked Albino to my silkie hen.
The the white Pullets produced did have black patches upon their pink skin.
The pullets were white, & pink skinned with black spots on feathers. The cockerel produced was Wheaten, with pink skin.
The...
They new what mottling was, but what they were studying was different then mottling.
The pattern Pie was characterized by its resemblance to Exchequer leghorn, but had more extension of white then usual.
All Sumatras are purebred, descend from the original birds that were imported from Asia in April 1847 by J.A.C. Butters of Roxybury, MA. There were more importations by others in 1850-52.
Only Sumatras that aren't really original is the bantam variety.
Okay, sounds good.
My mom's OEGB/Phoenix cross has white legs, with blue spots, but he's Blue Birchen. So blue diluted his shanks, & left blue patches, or is this feature only associated with mottling?
I found an interesting article on this subject that shares pied gene study with the breeding of a Barred Rock hen, & a Black Sumatra rooster. It's a very old article, but there was extensive work done on the experiment, & results have been consistent.
I may test out what they did, & see what...
Mottling based PieBald gene.
What would be a true pied gene?
I did ask if my bird was just mottled, what mutation would it be, but nobody answered that.
