Genetics of Welsummer x Easter Egger Mix ?

[SwampQueenChick]

We know the genotype of the hen, which is basically wildtype(as found in Jungle Fowl).

We can can tell the rooster's dominant gene that are expressing(as in color) such as he is heterozygous extended black(E/ possibly wheaten or eb), and Blue which is Bl/bl+ he is golden S/s+ at the sex linked s locus.

Will the chicks be sexlink? No, half of the females should be gold the other silver based and 50% will be at least solid black/blue the rest will have chipmunk or mostly chipmunk chick down.

What will be plumage color? half of the females should be gold the other silver based and 50% will be at least solid black/blue the rest will have chipmunk or mostly chipmunk chick down. The black/blue ones will mature to look like leaky blacks or leaky blues(like father), the chipmunk colored ones will grow to be either wildtype/partridge, 50% of those will have blue at the tail and flight feathers.

If the Oocyan mutation is linked to his pea comb, then at least 90% of all of the pea comb chicks will inherit the blue egg shell mutation.

Oh wow! Thank you for this. She will dive deep into this info you offered

Will the cockerel offspring be the same color as the pullet offspring?

As you know pullets have a different pattern than cokerels even on the same color type(for example Welsummer hens look different from Welsummer roosters), but half will look Black/Blue and half will have a similar pattern as Welsummer(some with blue tones on the black areas)

Thank you for answering!

I avoid hatching chicks from eggs laid by young hens. The eggs are often 1/3 smaller than the hen will lay after a few months. Small eggs tend to hatch chicks that have more problems than larger eggs. So as you suggested, wait for spring and then hatch some chicks when she is laying larger eggs and the weather is better.

I guess I wasn't aware of the fact that you can have more health problems with smaller eggs, but it does make total sense.

This is the result of a lavender Ameraucana crossed over a welsummer hen, and this is the only one that shows the self blue color , most came out a very dark pattern due to lavender having black genes ! When making crosses the rules never apply %

That hen is beautiful!

Also, we figured out that our rooster is a Cochin/Ameraucana hybrid! Sorry, forgot to update this post's comments with that information.
