10 Cornish X eggs in the incubator!

In reality a CX is not a hybrid/hybred ( When I was in school it was spelled hybred, somewhere along the line it changed and I did not,,,)

To be a hybred it would have to be a cross between a chicken and a goose or cow or pig. Whatever the parentage of a CX it is two chickens. Now the chickens were of different breeds, but not species. The CX is an amazing bird, it is bred to grow fast and have huge breasts with a good feed conversion rate.

Nonsense, a hybrid is not limited to a cross between two species...

From Merriam Webster

1. an offspring of two animals or plants of different races, breeds, varieties, species, or genera

From Encyclopædia Britannica

hybrid, offspring of parents that differ in genetically determined traits. The parents may be of different species, genera, or (rarely) families. The term hybrid, therefore, has a wider application than the terms mongrel or crossbreed, which usually refer to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species. There are many species hybrids in nature (in ducks, oaks, blackberries, etc.), and, although naturally occurring hybrids between two genera have been noted, most of these latter result from human intervention.

By definition a Cornish X is a hybrid...

I wonder if it is possible a "myth" as been spread upon us that crossing to CX's will not yield in another CX chick.

Not a myth at all fully based upon the science of genetics... Crazytalk gave you the basics but there is A LOT more to it when you get into the nitty gritty...

Here is an example, based on peafowl since I breed peafowl...

A 'hybrid' of a white and regular blue peafowl produces what is called a 'Split to White' they look like regular blue peafowl with one exception, that being they have white flight feathers... If I breed these same white and blue together I will always get this split to white offspring...

On the other hand if I breed two split to whites together (the hybrids) I will get 25% white (pair of white genes), 25% normal blue (pair of normal blue genes) and 50% split to white (one of each color gene)... Statistically only 50% of the offspring of the hybrids will be like the parents... And this is only dealing with on gene, if we toss in other genetic traits the statistical chance of getting offspring the same as the parent drops even further...

If you want to further educate yourself on the subject Google up Gregor Mendel (aka The Father of Modern Genetics) and his studies of F1 Hybrids and F2 Hybrids... His studies are the basis for modern day genetics and heredity understanding...

I am well aware of Mendel's work from centuries ago.

I understand we use the word hybrid to mean a cross between "breeds".

Your own definition:

hybrid, offspring of parents that differ in genetically determined traits. The parents may be of different species, genera, or (rarely) families. The term hybrid, therefore, has a wider application than the terms mongrel or crossbreed, which usually refer to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species.

All breeds of chickens are in the same family, same Genus and same species.

Not trying to get too far out in the weeds. But as your posted definition shows a CX is a crossbreed and not a hybrid.

Which gets me back to my original point.

If so why are you suggesting that breeding two F1s will create consistent offspring that exhibit full F1 characteristics? That fully contracts his studies that have been proven over and over again by modern science to be true... It's not a myth it's scientific fact, doesn't matter if the guy discovered it over 100+ years ago or not, he was correct...

Not trying to get too far out in the weeds. But as your posted definition shows a CX is a crossbreed and not a hybrid.

Only if you selectively quote part of the definition, taken as a whole the Cornish X is both a hybrid as well as crossbreed by definition...

Using the same quote but the part you conveniently excluded in your argument...

"hybrid, offspring of parents that differ in genetically determined traits. The parents may be of different species, genera, or (rarely) families." May I draw you attention to the word "may" do we need to define that as well?

What part of the Cornish X does not fit the definition of hybrid?

Fact is no matter how much you want to claim, breeding two F1 Cornish Xs will not produce Cornish Xs with the same F1 genetic traits, you will get F2s that might exhibit some F1 traits but many that will also exhibit genetic traits of their ancestry that was not exhibited in the F1s... That is why they are defined as hybrids (or crossbreeds) and not purebreds...

Apples and oranges, people. Don't start an argument on a friendly thread. We don't want it closed down. Be aware that we know that mixing two Cx's will not get you a grocery store bird. Not gonna happen. What we are looking for is a good mix of birds to get us a meaty bird. Start with a good LF bird that will get heavy and mix to a fast growing bird. CX's, New Hampshire,Pioneer to name a few.

 

[duluthralphie]

meepmeep.


Both of the CX's parents are chickens. Chickens are a species.
but not gonna argue, Don't care enough.

I agree no argument there and there never was...

A hybrid may or may not be of the same species, a hybrid is not limited to crosses between two different species, it can also be a cross within the same species of varying genetic traits, as is the case here...

Calling Cornish X either hybrids or crossbreeds is equally correct, neither is wrong...

Based on this thread, it appears not everyone knows that...

Look, this is my experiment, your more than welcome to watch them grow with us. If not, your welcome to move along. From what I've observed already, they DO grow faster then the other chicks.. did you see the pictures? The RIR was first hatched, the one next to him Cornish X baby is much thicker, wider and heavier and was the 4th hatched. Does that mean he's going to be as big as his parents? I don't know, that's why I'm doing this. Chickens are like dogs, you breed them to what you desire, color, height, temperament, etc... that's what I'm trying to do. Now I have 2 Cornish X babies who are about the same size as my RIR's so I will probably take the bigger bird and breed with my bigger Buff Orpingtons to get a great egg layer and a meatier bird. I just don't know yet, too early to tell...(experiment)

I'm not sure what the "political" correct word is to call these birds and everyone is making a good point on the scientific part, but all I hear is Blah Blah blah science science science Cornish... (from cloudy with a chance of meatballs)...

I wish everyone the best! I'm getting their outside pen ready today and I will post more pictures of their growth.

Good luck in your Cornish X experiments!!

Bahahahaha. Dana, I really like that. Some people get caught up in their own info that they miss the picture of getting a good bird with a cross of DP fowl and CX. The New Hampshires and White Plymouth Rocks grow well.

 

[Luvmybob]

LOL, LindaB220, I just couldn't help myself. Life is too fun to be sooooo serious...

Take care!
Dana

OH forgot to say, thank you I will look into those birds, I have never had New Hampshires or Plymouth Rocks but thanks for the tip! I'll be looking out for them this spring at our local Tractor Supply.

Because I have little faith in the CX's reproducing, I have a back up plan of crossing any CX's with a larger Dixie rainbow I am keeping just for that reason.

Also I apologize for getting caught up in semantics. It is because of my background, but still no excuse I should have let it go sooner.
