Crossing

[Turtle1626]

If I crossed a naked neck x cochin, is it better to cross the offspring with the nacked neck or the Cochin? Or should I cross the offspring together?

Depends on what your goal is. Probably try to avoid sibling pairings though

My goal is a naked neck Cochins. Or something like this

I'd breed back to the cochins, then. Be careful that the mixed birds you're breeding back to the cochins have the NN gene. Is your starter NN homozygous or heterozygous NN?

I’m not quite sure what should I look for?

Heterozygous NN birds have a little patch of feathers on their otherwise naked neck. Homozygous birds don't have that. Their neck is completely naked

Okay then thank you! I have a heterozygous nn

In this case, some of the offspring will bot carry the gene at all, and some will be heterozygous, like the parent. Breed the heterozygous NN cochin mixes back to the cochin parent

Okay since the nn are cochin mixes, but then will be crossed to a purebred cochin will I get 50% nn cochin and 50% Cochins I’m new to all this so I have a lot of questions

You'll get 50% NN cochin mix, and 50% non-NN cochin mix. You'll have to keep breeding for quite a few generations before you have a phenotypically pure cochin
