That's very interesting.
Sounds like some hybrid vigor there!

Yeah. What causes that?

I mean, it's not superior diet...lol.

It's fairly common when someone crosses two pure breeds of anything--chickens, cattle, corn plants, and so forth. The offspring often grow faster, get bigger, are healthier, and produce better. This doesn't always happen, but it's common enough to have a name: "hybrid vigor" or "heterosis."

If you want a more detailed discussion, here's a wikipedia article:

Neat! Thank you!

I have not, but you could expect beards & muffs, single combs, and if you use a barred roo all will be barred. If you use a barred hen and a non-barred roo, their chicks will be sex-linked with all the male chicks being barred.

When breeds are developed, the population bottlenecks. A large amount of birds are bred from a small amount of stock and the resulting birds are fairly inbred, but still functional. This goes for anything, essentially any domesticated plant or animal. All of them have some degree of reduced growth, health, and production due to inbreeding depression. Generally the newer a breed is, the worse the inbreeding depression.

But when you cross two (or more) different breeds, that is two different inbred strains of a species, the resulting offspring seem to be much stronger and healthier than their parents or other purebred members of those breeds, solely due to the fact that they are less inbred than the others. That's hybrid vigor in a nutshell, and it's why I prefer hybrid strains of everything, whether it be birds, goats, sheep, horses, or the plants in my garden.

hybrid vigor, by definition, is a cross between two species, and offspring are usually infertile.

No, that is wrong.

"Hybrid" has several definitions. You gave one of them (cross between two species), but this thread is discussing a different one (cross between two breeds.)

But either of those are definitions of "hybrid," not the two-word term "hybrid vigor."

"Hybrid vigor" is a commonly used term when dealing with livestock or plants. It is when when the hybrid offspring of two different breeds or varieties (same species) outperform either parent.

I understand how you are using the term "here". That is incorrect. Its DEFINED as "between two species". period. THAT is the CORRECT definition. but use it incorrectly, as much as you want.
