10 Cornish X eggs in the incubator!

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.

Stuff happens. But that's okay because we're back on the topic. Tell me about your rainbow. How big to they get? I've never seen any? Just pics

Gladly Here is a picture of "Rick" He is an average size Dixie rainbow. They are huge birds, even the hens are big. I was going to process some yesterday, Friday night I went into the coop to get the campers. I found only the Dixie rainbows were large enough to send to camp. I was only going to send the boys to camp and I only have 6 boys, I decided to put off the camping trip until more chickens were ready.

Rick is the one I am keeping for breeding. I know it is not smart to keep Rick, because he has crooked toes, but I will never show them. My Wife named Rick thus saving his life.






Rick was hatched on June 1st. I have no way to weigh him, I am guessing he is 10 lbs. He is solid, filled out legs and breast.

I put a blue poultry ring on him the other day I used the largest size, it barely went around his leg. It is nearly as thick as my year and a half old turkey tom.

Now if you are talking about losing some of the hybred vigor with subsequent generations, I may buy that if there is a study showing that. Otherwise I will stand by my original hypothesis that a CX breeding to a CX gives me a CX.

If breeding CX to CX gave you a CX, people wouldn't be ordering new chicks every couple of months. This isn't the first time people have tried to save a couple bucks by breeding the things to each other.


The genetics here aren't particularly controversial or complicated here, so I'm not sure why you're having such a problem with it - and yes, there are specific genes for some of these things.

That's not true.. Many people would have a hard time keeping them alive to breeding age.. and through the winter? That's really difficult! They have to be on restricted feed, and roosts cannot be high.. their weight will break their legs if they fly off a roost that is too high.

I've crossed a CX to a Barred Plymouth Rock. Next generation I'm using a Buckeye, because they are the fastest growing breed I have.

These things? Do you call a human baby an it? "These things" are amazing, fun birds with awesome little personalities that when raised correctly, they forage, jump, run and explore just like any other chicken.

I am with Duluth. When you breed Cornish X with a Cornish X they are still a Cornish X in my opinion. They may have slightly different traits than the commercial chicks but they are still a Cornish X. I mean think about it, if you breed an Easter Egger with something else, it is still an Easter Egger in the end. Why wouldn't you still call a Cornish X a Cornish X? What would you call it if not?

Because Cornish Cross is a not a breed. It's a product that's a result of several generations of planned crosses. Calling these chicks Cornish Cross, when they don't share those traits does nothing but confuse, mislead, and cause problems.

Cornish Cross are the result of a process where they go back atleast 2 generations, breeding Breed A to Breed B, and Breed C to Breed D. They then breed the offspring of these together. These breeds all have specific sex-link traits that they want to show up in the Parent Generation. That Parent Generation is then bred to produce birds that ALL are heterozygous for a whole bunch of traits. If you breed these, you don't get the same birds - you get birds that are homozygous for a lot of the traits.

Separate flocks of A,B,C,D are kept, linebred, and genetically tested to make sure that they keep the specific traits needed. A ton of research and money goes into these things, partly because a lot of the traits that lead to increased size are what are called "Lethal Alleles" - Basically if you get a copy of the gene from one parent, it has some affect, but if you get a copy from both parents, it kills you. One of the lethal alleles common in broiler stock is dwarfism in hens -broiler hens with the dwarf gene don't eat themselves to death, lay more eggs, require less food, etc- so many of the parent and grandparent lines carry it (normal type - fine, 1 gene - dwarf, 2 dead), but it needs to be gone in the generation that gets sold.

Cornish Cross is a term for a specific genetic mix - lets not muddy that term.

I suppose we agree to disagree with each other. What would you call chicks resulting from breeding two Cornish X? That question you did not answer.

Well the CX genes are quite strong, even when using a Barred Rock over a CX hen I get results that look very similar in structure to a store bought CX, but of course slower. I think one more generation and I can get it to 12 weeks butchering.

I hope you do not mind Aoxa, I copied this to the thread I started on CornishX's and my experiment. I wanted to comment and will not do it on this thread as I know luvmybob does not want her thread hijacked to this disagreement...

Thanks..

Hey everyone! I love the pictures they are awesome! I had to tell everyone that one of my Cornish. X babies is growing really big really fast, which I'm happy about. I'm gonna take a picture of him/her with my biggest tired.. weight..tired 4.05 oz., Cornish 8.70 oz.

13 days old. My other 2 Cornish x are bigger than theRIR but not as big as this Farsi. But again one was hatched 28 hours after the rest.

Take care! And all is good duluthralphie!
