It's just like with CornishX. 4 pure lines are crossed over generations to make an ideal mixed breedHello, I was checking out the isa browns hydridization, and I'm unable to really understand how it is possible to make isa browns. If someone can understand it, could you please see the attached photo and assist me?
Because it's a trade secret. Just like with CX. They didn't advertise it to the publicYes, but how is it that nobody could figure out the crosses?
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?

So the isa browns are just rebredding the delaware hens with Rhode Island Red (or other breeds that make the isa) or just getting different parents until you get the best egg layers?It doesn't even have to be a secret, if they just refuse to sell any of the pure lines (A, B, C,
Making color-sexable chicks is pretty easy. Making ones that lay as well as ISA Browns is not nearly as easy. That takes a lot of careful breeding work.
If you want color-sexable chicks, you can use Delaware hens with Rhode Island Red roosters. The daughters will lay about as well as the parent breeds do (probably not as well as the ISA Browns). There are quite a lot of other breed combinations that will also produce color-sexable chicks.
So is it more of the best of the best pure breed parents, not a mixture of breeds?It doesn't even have to be a secret, if they just refuse to sell any of the pure lines (A, B, C, D).

Pretty close, yes.So the isa browns are just rebredding the delaware hens with Rhode Island Red (or other breeds that make the isa) or just getting different parents until you get the best egg layers?
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.So is it more of the best of the best pure breed parents, not a mixture of breeds?
