Until yesterday I was a lurker at the The Coop for 3 years.

I always considered it the big kids playground, where I might add, I was much safer watching the game from the monkey bars .

I have popped in to look a few times, but I don't see that it is very active. Is there a search option somewhere? It looks hard to get around in am I missing something?

If you are logged in or have created a user account, you can use the search function and no it is not as fast paced as our most wonderful BYC, but you get different traffic there from folks who may not visit BYC.

Right, so then each bird you have (with the exception of 2 the carnation and the non carrier) has one copy of the defective gene in its gene pair...when crossed to another carrier will produce carnation. The non carrier....crossed over a carrier bird that only has one copy would produce a single non effected comb.

Ok, that's pretty much what I've been trying to say. It takes two any way you want to look at it. So, in theory, are you saying that they can carry one gene for it that is harmless (recessive), and not pass it on to another with a recessive gene?? What if one carries one of each, recessive and defective and you breed that bird to a clean bird? No carnation, but now the offspring carry one copy of the recessive, and one copy of the defective?? This is making my head hurt!

Does David Hancox ever get in there? Wonder what he has to say on the matter??

Maybe because it was unknowingly and continually bred in in some instances that it stacked up the genetic odds in its favor and now instead of being only a few birds out there that were carriers or expressed it......many many many more birds now carry 1 copy of the defective gene in their gene pairs and has basically spread like little 1 gene'd wildfires.....with the limited amount of stock out there, it is no wonder that we are seeing more and more carnations.

YES! I would consider the boy with the HUGE comb to have some stacked genes, my term, double dose. Watching auctions on ebay, you will see more and more Carnations being expressed. God only knows how many carriers there are! With the already tiny gene pool in this country, I beleive we will all have it in time, unless you got good birds from the get go, and closed your flock to all outside birds! I wish I was more adept in genetics, some of this is hard to grasp for me. You have more of an understanding and the verbage to go with it. Me...not so much!

Think you feel like a kid on the monkey bars? You should be in my skin!!

Well, he wouldn't have a double dose, as in 4 copies of the gene.... but rather both of his gene's in that particular pair of genes are defective.

Gotcha! Thanks! Now I can see where the percentages would come in.

Please do write him. I haven't seen him in here in a long time.

Hmmm, this is interesting. He must've been the one that responded to my intial post on the MCCU group about the Barnies. I don't know if that would be true or not, where did he get his info? How many birds has he produced from this?? Here, even though the hatches are small, the Carnation seems to be dominant over the single comb, unless all of mine are doubled up on the "defective" genes?? If a carrier is bred to a carrier here, I get all carnations, albeit with small hatches. When the breeding was a carrier to an expression, I got those HUGE tree looking combs, or what I call the "double dose". Either way, it totally sucks that we have to worry about this in the first place! Is he doing the crossings on purpose, or did it just pop up with his flock??

I'm not sure, I have a private email into him with some of those questions.

But with 3 out of 4 chicks that would hatch either being a carrier and/or effected with the carnation.......I can see why it pops up more than what you would think it should....but with 3 out of 4, it seems the odds would be in its favor.

I would be highly interested in his breeding process for determining who is who in the ratio of chicks. If there is a possible way of knowing for sure who carries the normal genes I would think it would all be in test mating, no? Anyways..Keep me informed ma'am..I lurk over at that forum but am too chicken to sign up cause...I am not good with the technical speak haha

He did not determine the ratio of chicks......I used that as an example from some information I got off line about autosomal recessive and its inheritance.

I'm just going to go with the assumption that all of mine are at least defective carriers. At least the hens are. The hard part is going to be housing all the hens seperately, and collecting eggs from each girl, all bred by one roo. Clear the roo for the genes first, then take him to the different hens. Lots of note taking!
