Interested in Eggs from grandparent stock of cornish cross..

[FarmersFresh]

Hello, I am wanting to see if I can purchase some fertile eggs from the breeding line of the grandparent lines of the cornish cross( ross 308, etc). If anyone can give me more information on how I can purchase some eggs or even the grandparent lines to produce the other lines to produce real cornish crosses, i would be very very appreciative.

Thank you.

All you have to do is get the chicks from the hatchery and raise them on a feed restricted diet (Ross and Cobb both have outlines of how to do this) so that they are able to mate and produce more normally. Google "Ross Breeder Management" and the info will come up.

Thank you Kellyhm for the information.
I thought it is proven that it isnt possible to get the same results in the hyrids? Can you give me more information on this and if you have seen the results?

Thank you for the help.

I learned all this during my poultry rotation in vet school...we visited several farms and that's where I got the info. I took some eggs home and was going to raise them that way, but I hatched all boys.

They went in the freezer instead.

I see so it is possible to do that I guess. Is there a reason why then the companys that produce the eggs like aviagen, and other people who raise these chickens say it isn't possible to do this with the offspring only with the grandarents lines can be possible to acqure the real cornish cross?

So if I were to purchase some cornish crosses from ideal poultry and raise them using the management guide, then the female would be able to be good layers and the male still produce offsprings that are real cornish crosses?

Thank you for the help.

I'm sorry but if someone is able to get you grandparent eggs....then you can bet they will be in trouble with the company.

It is not possible to raise the broiler birds (PS offspring) to lay eggs as well as the parent stock.

Actually, if you wanted to REALLY get a good start, you'd need to get Great-Grandparent Stock (GGP) because you will need four separate lines in order to get the same results.

I see what you're trying to do...but the best way to get started is to become a grower for the company. But, if you wind up selling the eggs/chicks to someone OTHER than the company for which you are growing for...you risk being fired, stripped of your land and you will have voided a contract and guess what...you = cleaned out by the court.

thank you for the post.
Well that is why I am asking because I was confused but now I am much more confused.....so what is it with what kellyhm is saying with breeding the same offsprings together using the management plan from aviagen? Will the offsprings still come true in being cornish crosses or will the result be different?

Has anyone tried this and seen the results comparing?

This is exactly what I am wanting to know because it seems there is a mix of answers...so......

1.is it possible the way kellyhm said by just using the breeder management plan for the offsprings and the offsprings will come true in results?...or

2.Is the method above not true and its really just making these four lines, etc etc to achieve the results for a cornish cross??


I really would like the answers to this as I am confused on how this would work and would like to see what I can be able to do in maybe purchasing some eggs either from ggp, or just cornish cross eggs to experiment myself.

Thank you, and please do help me out.

The broiler birds (final offspring) will not be able to reproduce well at all. They will lay a few eggs IF you can get them to breeding age.

The rapid growth/maturing and the actual size of the bird means that the egg production is going to go WAY down. The males will not breed the hens as, well...they're more interested in other things. They will not fight for dominance as normal birds do because they are just designed to gain weight rapidly.

Getting the actual GGP stock is the way to go if you're wanting to make your own lines. BUT AGAIN. I caution you. If you steal eggs/buy eggs from a breeder of a company (I'm assuming Aviagen as that's who you're mentioning), you could face retribution.

The "hybrid vigor" (rapid growth) seen in the broiler birds is because of crossing the four lines.

You have 4 lines. Each of those lines is bred separately until a foundation flock is started. Once ready, 2 lines (bred for the same purpose...either male line or female line) are bred together. Usually, there are a few more generations to preserve the lines for the "in case" factor. These are the grandparent stock (GP.)

The GP stock are then bred together to give the Parent Stock. The Parent stock are then bred together (female and male lines converge) to produce the broiler birds we eat.

I see well this is what I thought it worked like. Then is what Kellyhm reffering to the breeding management is only for the Great Grandparent breeding lines then right? I see well then so all this meat bird is really just really high extensive breeding isnt it? Is there a way they make it easier in breeding without having to have the ggp lines? So do they actually always start from the beginnning at GGP lines to get the results or do they have a short cut?

thank you very much for the help and assistance.

Honestly, I do not know what kellyhm is referring to?

Yes, the thing to the meat bird is being VERY selective in parent stock, choosing the largest males that still show fertility and willingness to breed, and in the females, choosing the largest females that also have somewhat good egg production.

In industry...there's not. They are constantly tweaking the lines in order to get a better bird in order to compete with other companies.

By maintaining their breeding flocks, they are able to at least insure themselves for future broilers. That is about all the shortcut they can expect...unless a company decided to "gift" them a recipe for insta-broiler!
