What's the difference between Red/Blonde Sex-links and ISA Browns?

[Mary Of Exeter]

We've had countless Sex-links over the years, mostly the typical "Black stars", but also quite a few Red and Blonde Sex-links.

Now I see these ISA Browns everywhere. Are they not the same thing as all my other Sex-links? Just perhaps made with different breeds? Any difference in the eggs and laying habits? Or is it just another of the countless names for Sex-links? (why the heck do they have so many names!? Red stars, cinnamon queens, red comets. Then I just call them either red or blonde sex-links. And the blacks, black sex-links, instead of black stars

) I have a feeling the different nicknames have something to do with the amount of red, blonde, and white on the birds?

Tired, or just bored?

From the reading I've done it seems ISA Browns are the offspring of Rhode Island Reds and Rhode
Island Whites.

As far as red stars, cinn queens, etc, they come from a red rooster over a white hen, such as white rocks, colombian rocks, etc.

Seems the hatcheries make up catchy names for their red sex links, and it doesn't have much to do with the birds they use to breed them.

I know this isn;t much info and it's coming from memory, so I wouldn't quote me on it. There's alot of info out there if you care to do some research.

I seem to remember that ISA Browns are a proprietary name ... I.S.A. stands for something to do with the organization that bred them.

I popped over to wikipedia:

History

ISA stands for Institut de Sélection Animale, the company which developed the breed in 1978 for egg production as a battery hen. In 1997, the ISA Group merged with Merck & Co., forming Hubbard ISA, so the breed is sometimes called Hubbard Isa Brown. In 2005, Institut de Sélection Animale (ISA) and Hendrix Poultry Breeders (HPB) merged. Institut de Sélection Animale SAS, France (ISA SAS) is now an operational centre of Hendrix Genetics. In March 2005, Hubbard was purchased from Merial Ltd by Group Grimaud La Corbiere, SA.

A red sex-link is a gold gene roo over a silver gene hen.
Silver gene is different from white genes , they may look the same but they don't work the same. Sliver is sex linked, white is not.
SLW, Silver penciled, and some white breeds are silver genes.
RIR have the gold genes.
