Trout Indian Runner Genetics

[Duck Hill]

: D

Brown + Blue = Beige (or light tan or cream).

Hmmm this makes me wonder if my fawn and white runner dad is the source of the blue instead of the pekin.

That should not happen. My understanding is:

Regular trout is M+M+ li li without any Blue gene.

Blue trout is M+M+ li li Bl (one partially dominant blue gene).

Saxony is M+M+ li li Bl Bl (two blue genes).

However, there seem to be shades of each color, and that can really affect how a duck or drake looks.

I thought the drakelet on the left, below, was a "Blue" harlequin in color because his spots looked grey in color, and because his coloring is so pale as compared to his "Not Blue" brother.

However, when his wing feathers came in, he had bright blue color on his speculum. You can see it peeking out of his wing below (drakelet on the right side). This means he does NOT carry the "Blue" gene - just two harlequin "lih" genes, the same as his brother above. I don't know what makes his color so light compared to a normal harlequin duckling, but it CANNOT be a "blue" gene since he has the blue color on the wing speculum.

Below, you can see the blue color peeking out of his wing (if you make the picture larger). The duckling on the left in this picture is half-harlequin in color and carries a light gene, so probably M+M+ and lih li.

Do you have pictures?

I hatched 5 runners from the Apricot Trouts Project at Dusky Feathers. She states that there is a chance of hatching Blue Trout. I was lucky to hatch 4 hens and 1 drake - the drake is lighter on the back with a much darker chest and his head is lightening but one of the hens is quite a bit lighter than the other hens. Most have an obvious apricot colour but the one in question has a large amount of pale blue/silver. This same duckling was darker than the rest at hatch. I'm curious if this hen is a Blue Trout or if it's just a normal variation of Apricot. I can't seem to find many pictures of Blue Trout anywhere.
