Breeding Cornish X Rocks

Pics
Farmers have not been using line breeding in poultry until the 1900's. Farmers crossed chickens with other chickens there were no breeds. Fanciers made the breeds not farmers.....

A commerical bird is not unsustainable.

I have a great friend that works with Light Sussex. She raises 700-800 throughout the season. Her breeding flock consist of ~80 birds. Various culling takes place at a certain time periods for crucial weights.
WHAT'S YOUR POINT? Seems irrelevant to me. I do doubt that you know what happened 100 plus years ago. But, I know for a fact in order to take a crossbred bird, and to stabilze the gene pool enough for it to replicate it'self- that bird had to be linebred towards that goal for many generations. It doesn't matter who did it- IT HAD TO OCCUR!

I guess I view a hybrid 4 way cross that cannot reproduce on it's own, or replicate it'self-- as unsustainable. Maybe your dictionary definition is different?
 
All you have to do to know what on in the old time is talk to the really old school farmers, and read the books from the 1700's-1800's.


Lines A,B,C,D are pure bred - so IMO 4 way crosses are sustainable.
That's about as accurate as research using Wikipedia...

I have books from the 1800s, they are interesting...

I'll assure you that there are no 'purebred' lines involved with the Cornish cross broilers of today. There might be 'purebred' lines of Broiler birds, and purebred meaning able to breed true...

But, I'll assure you- as a Cornish person- there are not any purebred white cornish floating around in the gene pool of CX birds.

Those birds have advanced enough, with enough millions of breeder birds, that I'll guarentee they could never be replicated and started over from scratch. Way too much has been overcome in the past 50 years, or however long.
 
Hello
kfacres..I am gonna go out of the box. I personally think think the CornishX. Really has not changed much since about 1952. Well the genetics has. And the rate the grow. Has been at an alarming speed. But I really think the Pedigree breeding lines. Are still what they were. Not many out side this multi Billion dollar business. Do know the industry secrets.
They will tell you it takes 4 pure lines. And about 4 years.
That is my opinion. I buy the Cornish X almost every 2 or 3 months. And I try to look them over. And I am Truely amazed. At the way the look. The feathers and the body. Really look like a Cornish. But Cornish do not grow this fast nor do they have the straight comb. Obvious traits.
I have tried for many years to get articles and pictures. Of Industry Cornish breeders. And I only came accross 1 picture. And that is a Russian President or leader in the 1950slines getting some of them.
Any more info would be great. That is my take on this. A multi Billion dollar business. Thank you......Nick

No the genetics have changed - only the P1 generation (grandparent) is pedigreed - and at that only some of the breeders. The genetics in chickens need to be changed every so often.

It takes way for than 4 years to get a commerical broiler bird from scratch. And 3-5 years turn around to get a commerical bird from cultivator stock. You will not get information from the industry. The idea that there are a lot of secrets to breeding these production birds is rather foolish - because there are almost no secrets that can't be obtained with the right network. But you have to be willing to track these people down - you have to be-able to tack them down. The information that is not on the internet is not there for a good reason - It's complicated and it's not a science.

There is a lot of information that I retain - I was more or less told what I know I should keep to my self. But I can tell you this - to make a marketable bird it takes at least 10-12 years - that is knowing the theory, it takes thousands or tens of thousands of birds, It's all about how good of a breeder you are.

There was an Amish poultrymen in PA that developed a giant silkie broiler - got scooped up by a large genetics corporation. The skilkie broiler flock now resides in BC,Canada - somewhere's.
 
Call Duck
My good friend told me about doing the Silkie Broiler. Like you have mentioned. I know he is a very good breeder of chickens. But he will not be doing that. I would like to see what they look like.
And if you would like to send me info on the CornishX. You can email me if you like @ [email protected]...Thanks Nick
As I have already attempted my own back yard Cornish X.
