Genetics...it's all greek to me

[Cryss]

I have a small passing interest in chicken genetics on the very basic simplistic level as pertains to my tiny flock I've had only since November although I have a feeling that could become an obsession. I don't speak genetic-ese so what I read makes no sense, all the letters, numbers....huh?
I'm curious what my single Lavender Orpington Cockerel might produce in bird color and maybe egg color in one instance. I have 2 Buff Orpingtons, 2 Barred Rock, 1 Silver Lace Wyandotte, and 1 Easter Egger. Any thoughts?

I'll try to restrict my genetics-ese to saying that the cockerel is based on black and the Lavender is a recessive gene so you will not see it in the first generation. But some will sip though.

Buff Orps - In theory you should get solid black chickens but some of the modifiers in making Buff can do strange things when mixed with black. You often get a lot of yellow or sometimes even orange in the offspring. You may really like some of these. A brown egg.

Barred Rock - These will be sex linked. The pullets will hatch solid black and grow up to be solid black hens. The cockerels will hatch with a white spot on the head and grow up to be barred. Brown eggs.

Silver Laced Wyandotte - I'm not familiar with these but the genetics calculator says the offspring will be solid black. I'd expect some red leakage, especially in the males. Brown egg.

Easter Egger - An EE does not have any specific color or pattern genetics, they can be anything. I don't have a clue what the chicks might look like. If the pullet lays a brown egg, you will get a brown egg-laying pullet. If she lays a blue or green egg, you might get pullets that lay green eggs, you could get some that lay brown eggs. That depends on what genetics the EE has.

Good post here, I have never seen the cross or reference to such cross, but I suspect a very solid black bird will be produces, E/eb with Ml/Ml, Pg/pg+ would produce a very black bird indeed

eb is a direct mutation of Extended black, so E/eb birds will behave differently from E/eWh or E/e+, with the help the melanizers on the laced parent like Ml, Pg will produce a very melanized bird, it would be interesting to know if heterozygous columbian Co/co+ will have any effect on E/eb, I doubt it, but I know E/eWh do(black sex links)

Just a caution, I read some of your saga about Roopecca (your lav orp roo). Honestly, I would avoid hatching chicks from him. With as many problems as you've had with him (particularly the crop issues) I don't think he would father hardy chicks. Unless you have another Lav Orp roo......

Yes, I've thought about this. Thanks to this site I don't have to hatch just satisfy my curiosity. IF any of my gals was able to conceal and hatch from Roopecca I suppose freezer camp could handle any problem offspring. I seriously doubt they could conceal well enough.
