Hi,
We have a chocolate Orpington hen and a Cuckoo Orpington rooster (parents were, we were told, a black orp rooster x with a lavender cuckoo hen). My question is if I breed the two together, chocolate hen and cuckoo rooster together could I get somewhere close to a chocolate cuckoo down the line? I can't seem to find genetic info on cuckooing.
Thank you

Chocolate is sex linked just like cuckoo/barring.
Cuckoo works just like barring.
If you're correct about what the parents of the rooster is then that cross will produce about 50/50 cuckoo and non cuckoo since he only carries one copy for cuckoo.
He also carries one gene for lavender so about 50/50 on split for lavender and no lavender genes.
Hen will pass one gene for chocolate to all cockerel offspring. They will look black but carry chocolate.
No pullet chicks will get chocolate genes.
It will be random on which chicks get which of those gene combinations so possible outcomes would be.
Black pullets
Black pullets split for lavender
Cuckoo pullets
Cuckoo split for lavender pullets

Black split for chocolate cockerels
Black split for chocolate and split for lavender cockerels
Single gene cuckoo split for chocolate cockerels
Single gene cuckoo split for chocolate and split for lavender cockerels
All cockerels will be split for chocolate so they have potential to produce chocolate pullets but you would have to use your chocolate hen or a future chocolate pullet to ever produce a chocolate cockerel.

Wow, okay. Lots of possible outcomes. I guess I'll try him and see. I have no hen to pair him with but he's such a sweet and gorgeous big boy that I'd like to breed the traits. Thank you for your answers :)
