Buff Barred Cochin

Thank you.

It is an easy project. Breed buff to barred, male offspring to buff females, select for type & colour from there.

Hi,
Where do you get a barred orpington to breed the buff too?

 

[horsechick]

so you use barred hens of any breed? preferably clean legged and same color legged as an orpington?

Ok , I have a question then for Steve. I hatched out a couple buff barred roos a few months ago-originating from your stock. One I gave to a friend. He had very good dark barring. The other has pretty light barring. He is still too young to beed. Would it be wise to put him in with the other mature males and let him breed to his mother and aunts to improve the female barring [which I don't have yet]? Why do you think the lighter barred males are double barred? My genetics knowledge is limited so bear with me here.
Thanks, Patty

It's becuase the lighter ones are homozygous barred with two copies of the barring gene, These will give all barred chicks when breeding to a non barred female, but the males produced would be heterozygous barred, only having one copy of barring and would be dark barred.

If a dark ( het) barred male is bred to a non barred female, only half of the chicks will be barred and half will be non barred, not sexlinked though.

Ok,so breeding my light double barred roo to his mother and aunts will result in 1 /2barred female as well as 1/2 barred males. correct?

So what would the big gameplan be here?

I am afraid of too much inbreeding. I do have buff cochins, & barred cochins that I could outcross to. What would be the wisest move to continue the beautiful barring, but avoid lots of potential problems by working with a small gene pool? Right now I have: 2 dark barred mature males, 4 non barred breeding females, 1 "young " lightly barred roo
Thanks !

I have 1 light barred roo from the eggs I hatched. I'm planning on breeding him to unrelated solid buff hens. If he's homozygous for barring I'll get all barred chicks and if he's heterozygous I'll still get 50% barred.

No, if your roo is light ( homo) barred and his mother and aunts are non barred, then you will get ALL barred chicks, but the male offsring would be dark ( het) barred.

It would be best to breed to pure good quality, buff hens, not barred or you are going to go back to producing non gold chicks.

I am working on a Buff Barred Orpington project, it would be a while before they are up to where I want them though.

Another thing to consider is the buff coloring...a lighter roo could possible just lighter buff color and not necessarily homozygous for barring. Just something to consider since buff can vary in shades of light and dark.

I know some have used white Plymouth Rocks to increase size in their Bff Orpingtons. Would it then work to use a Barred Plymouth Rock to get the barred gene and increase size?
