Theoretically (sp) I know you aren't supposed to, but I've also heard that breeding a frazzle to a straight feathered bird is the "for sure" thing, so thought if that happened I could give that a try. And in the case of having a bird that was too curly and wasn't thriving, I would cull and have chicken for dinner...

That probably sounds really harsh, and I hope that's not the way it turns out. I'm hoping to only breed once and get a good frazzle out of it and not have to take chances of producing a unhealthy bird, but from what I've read on here, you can end up with a decent frazzle bird....

I will check out the kippenjungle site...thanks so much for the info! I am getting way too hooked on the chicken breeding thing

I already had to build another small coop for my silkies and at the rate I'm going I'm going to have to build another one

Thanks!

So what happens if I can''t understand the beginner friendly version, lol! Wow that's a lot to sift through...maybe I will just stick to raising hobby/PQ birds

I guess I didn't realize the crazy number of variables to chicken genetics....

Thanks again for the info!

First learn some of the basic terminology and concepts--it's pretty much the same for all creatures. Then start with one gene and try to understand it. Blue is one of the most commonly learned genes, and is fairly easy to understand compared with some of the others. Then gradually add another gene and another.

Seriously, just keep reading the same stuff again and again, and pick up a little more each time. It's a lot to learn all at once, somewhat like another language. It helps to learn some basic terminology first, like allele, incomplete dominance, etc. OOOHHH!! I just thought of a question! Is there anything known to be codominant? Anyone reading this thread? Don't mean to add more confusion, OP. Codominance is when two different alleles are expressed independantly. Like, if red and yellow were codominant, and both present, you would have a bird with both red and yellow feathers, as opposed to incomplete dominance, which would give you an orange bird. Anything codominant in chickens?

Not that I know.

Okay so one other question...after reading up a bit on chicken genetics, I'm a bit confused about the generational breeding. You know F1, then F2. Just so I understand this correctly, is the intention to keep breeding offspring to each other until you get the desired traits? That's how it sounds to me....Don't you have to introduce new bloodlines or worry about inbreeding? Is that an issue with chickens?

Thanks again!

It can be done that way, but often it isn't.

In breeding & a build up of unwanted genes can be an issue with chickens just as anything else. With careful selection it is far less of a problem than one might imagine.

Start off by keeping your red birds separate from your black birds. For blacks, you can use splash & blue to work with. It really depends on what varieties specifically you want to produce. But instead of killing yourself genetically, why not just purchase compatible varieties and learn as you go from them?

Co dominance is most often expressed on the cell level and not in gross morphology ( feathers,etc). For example in henny feathering. With henny feathering- the henny feathering gene is turned on in males and produces an enzyme called aromatase- this protein converts testosterone (male hormone) to estradiol (estrogen or female hormone). If a male is heterozygous (has only one henny featheing gene) for henny feathering he produces 1/2 the amount of aromatase in his skin as a male bird that has two henny feathering genes. So you do have co dominance in cellular activity but not on the gross morphology level. A male with one henny feathering gene or two henny feathering genes has henny feathering so the gene is considered dominant in males.

Pea comb is supposed to be incompletely dominant but from my working with heterozygous pea combed fowl it is the only thing I can think of that appears to be codominant. The top of a male comb looks like a large pea comb and the bottom of the comb appears to be a single comb, same thing on females. So both genes are being expressed.
