Columbian x Black cochin= ?

[AWChickens]

I've been playing with the genetics calculators and want to make sure I have this right. If I put a black rooster over a columbian hen, I'll get 100% black chicks?

I have 4 black cochin hens and one columbian cochin hen. Saturday I'm getting a gorgeous black rooster from iluvmychicks

I'd like to put them all in one breeding pen, but not if I'll get funky colors from the columbian hen.

Thanks in advance guys!

It is not a good idea to breed the columbian bird with the blacks if you intend breeding from the ffspring or selling to someone else who might breed them, because the chicks from the columbian will be carrying unwanted genes.

That's what I was afraid of. I at least want to hatch out some to keep for myself. I'm new to cochins and was having trouble finding more info on the columbian gene and how it works. Sigh- I suppose that means I'll have to keep a buff cockerel or buy a columbian rooster.

 

[AWChickens]

Thank you though.

Do you know what happens with that recessive gene? Would it only become evident if you crossed away from black? I'm not going to experiment, I just want to learn how this all works. I'd been making punnet squares for the horses for 10 years and I've got each of their modifier genes worked out....but birds are a lot harder to learn

It's more than one gene. Either wheaten or brown both of which are recessive to extended black. & Columbian which is incompletely dominant but doesn't show much on extended black.
It is also possible that offspring from the cross would have leakage.
If you used the birds in your black flock, sooner or later you would find birds hatching which were not black.

Could you recommend a good genetic text for poultry? I haven't found one yet that does a good job of explaining all the modifiers.

I am working on a book that explains things in detail by using graphics, pictures, tables and charts. I am working on sex linked traits at this time. I started the section on sex-linked traits thinking I would only write 5-10 pages; I am now at 50 pages ( font is 12) and still writing. I still have lots to write about. I have no idea when I will get finished. I started writing the book a year ago.

I spent 25 years teaching biology and chemistry( just retired). So I do know a thing or two about teaching. I am writing the book assuming a person knows nothing about biology.

Wow. Sounds like it will be a really interesting book. Good luck.

Great! That sounds like I might be able to understand it.

Two things Tim. My room-mate is a retired lawyer and an awesome editor if you need a second set of eyes.

And I can offer total moronhood for a sounding wall if you'd like to vet the book to a willing and suitably untaught audience for feedback.

Laura writes for a living now - as a proposal writer but she really is an excellent editor. I'm an excellent untaught mind... I'd be happy to offer both our help, if you'd like. And then I want to buy the book immediately when it becomes available.
