Chocolate Cuckoo Orpington x Bielefelder

[Utwo Jereo]

If I cross bred a Chocolate Cuckoo Orpington rooster to a Bielefelder hen, and if I cross bred a Bielefelder rooster to Chocolate Cuckoo Orpington hen, would the resulting chicks be the same? What would the chicks look like? Would both crosses result in auto sexing chicks?

Only the results of the first cross would be sexlinked, neither would be autosexing. From the first cross, male chicks would be black cuckoo with leakage, female chicks would be chocolate cuckoo. From the second, all chicks would be black cuckoo with leakage. Chocolate is a recessive sexlinked gene.

If I cross bred Bielefelder Hens to the following roosters, would any of the chicks be auto sexed? Roosters: 1] Crele Cuckoo Orpington Rooster, 2] Golden Cuckoo Maran Rooster, 3] Cream Leg-bar Rooster 4] Wel-bar Rooster? What would the chicks look like?
If I cross bred Bielefelder Hens to the following roosters: 5] Buff Orpington, 6] Lavender Orpington and 7] White Orpington, what would the chicks look like?

 

[Amer]

The chicks would be autosexing if crossed with those roosters if the strain the roosters come from have been selected for autosexing qualities and that those genetics are compatible with the Bielefelder. I am certain the golden cuckoo Marans will not produce autosexing offspring and the Crele Orpington won't either.

Crossed with buff Orpington you'd get black tailed buff barred males and black tailed buff females.
Crossed with Lavender Orpingtons you would get black barred males (with leakage) and black females.
Crossed with white Orpingtons it is impossible to know what you'd get because white Orpingtons are recessive white and recessive white hides whatever genetics the bird has.

Chocolate rooster to non chocolate hens will be sex linked as only hens will be chocolate. The males will also be double barred and the hens single.

The other way around will only produce barred, black offspring, but the males could be lighter than females, so can be sexed with about 70% accuracy.

You’ll get some interesting offspring anyway, big chunky birds probably. You could breed the offspring together and eventually get a line of chocolate based creles which can be autosexing and breed true in colour.
