Genetics of Welsummer x Easter Egger Mix ?

[SwampQueenChick]

We bought Welsummer hen from Tractor Supply ( stock photo below - not mine )
Rooster is possibly Easter Egger mix so we are told.

Would like to breed the two of these for chicks.
We would like to know the possible genetic outcome of these two.

Will the chicks be sexlink?
What will be plumage color?
What color eggs will their offspring lay?

You are asking for a genetic prediction where half of the genetics are unknown.

The rooster "may" carry the blue egg gene. If so, it is linked with pea comb. The feather colors are gray/black/silver with gold leakage and mahogany/gold/partridge. The females will tend to exhibit partridge phenotype. Males will tend to exhibit mahogany, especially on the wings. Presuming the male carries the oocyanin gene, 1/2 of the females will lay some form of blue/green egg.

edit: wanted to add that partridge phenotype is NOT the same as partridge coloration.

I understand it's hard to predict. My young daughter has been studying chicken genetics and asked to post the question! I'm just excited she has found this interesting. I appreciate your reply.

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!

Why dont you breed them and then post here for us lol your cockerel might be an olive egger he has feathered feet thats all I got lol but heres a chart that could maybe help this chart works if your rooster is an f1 possibly

This helps a lot thanks! We will definitely post the outcome! We will wait til spring when she is older. Don't want to deal with chicks during winter
