It doesn't even have to be a secret, if they just refuse to sell any of the pure lines (A, B, C, D).Yes, but how is it that nobody could figure out the crosses?
The other line must be red, to make the color-sexing come out right for the end product. It might just be another line of Rhode Island Red or New Hampshire.(A)RIR/New Hampshire, (B)White Leghorn/White Rock, (C), Silver Leghorn/White Leghorn.
Females would be White/Silver birds.
I don't really see many people crossing RIR w/ leghorn and it sounds like an isa brown mix to me.....people like to use RIW X RIRIt would make more sense to use Leghorn due to the higher production rate.
I've seen various shades of brown in some cartons at the store. Copper brown, to cream.
I suppose I don't know for sure what color it was, but the current Cornish Cross are definitely white, and I've never heard of "Cornish Cross" in any other color.I thought it was barred Plymouth
The White Leghorns that are commonly available now cannot produce sexlink chicks. They have Extended Black and Dominant White, so crossing them to any rooster will just give white chicks for both males and females.RIR X White Leghorn was the original Red Sex-link cross. Now there's various other combinations creating different lines of sexlinks.
Understood thank you very much.Pretty close, yes.
What they probably really did:
Breed white hens and red roosters, raise a bunch of daughters, keeping track of which daughters came from which parents. See how well the daughters lay.
Take the white hens and the red roosters that produced the very best daughters, and breed each of them to mates of their own color, to get more white chickens and more red chickens.
Using that new generation of white chickens and red chickens, breed the white hens with the red roosters and keep track of the daughters so you can find which parents were the best...
Repeated over and over, for many years.
They eventually ended up with the current set of chickens, that are probably not recognizable as any specific pure breed, but that are very good for producing ISA Browns.
Looking at that chart in the first post, I would say that A and B would be two lines of white chickens. Breeding them together gives the white hens that become the actual mothers of ISA Browns. C and D would be two lines of red chickens. Breeding them together gives the red roosters that become the fathers of ISA Browns. Each year they are also breeding A roosters with A hens, and B roosters with B hens, to get the pure As and Bs they will be crossing next year (and C roosters with C hens, and D roosters with D hens.)
The only thing that keeps you from doing the same thing yourself: space to raise a lot of chickens, money to pay for the housing and feed for all the chickens, and how much time you are willing to put into the project.
Sort of yes, sort of no. Each of the lines of chickens (A, B, C, D) would be like a breed, in that it can reliably produce more chickens like itself. But it is not a breed that has a name, gets sold by hatcheries, raised by private breeders, entered in chicken shows-- so in that sense it is not really a "breed" as we usually use the term.
Whats mixtures do you have? For A B and C? Also whats breeds can you make isa browns? And what breeds to make CornishX?I have an idea what the mixture is for A,B,C, but can't think of what D would be, unless it's a repeated mix of A, or B.
What would you expect?I have an idea what the mixture is for A,B,C, but can't think of what D would be, unless it's a repeated mix of A, or B.
(A)RIR/New Hampshire, (B)White Leghorn/White Rock, (C), Silver Leghorn/White Leghorn.Whats mixtures do you have? For A B and C? Also whats breeds can you make isa browns? And what breeds to make CornishX?
To make CornishX (also called Cornish Cross, or Rock Cornish Cross, or other variations of those names):And what breeds to make CornishX?
