The Classroom @ The Coop....a fantastic place full of All Knowledgeable Chicken Guru's from all over the world.

I commented on an old post of someone elses inquiring about the comb modifiers of the Penedesenca and this gentleman responded with his findings in his own birds.

So if I do a search for this website it should come up?

Yes, but try this link. If it doesn't work I will try it again.

Well lucky me, I seem to get them all, regardless of the odds or percentages!

I still want to pair up the brother and sister with the tree combs to see what those monsters would look like! They should produce combs that look like a Palm tree!

Yes, that link works. Give me strength, I may have to jump in there..

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.

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

Here is what I've gotten here so far. Please note, that I am assuming the original hens are all carriers, with the exception of the one that HAS a carnation, she is obvious. Since the chicks were born, I lost one of the original hens, so now I have one carrier and one expressor.

Carrier x Carrier = Carnation combs in all chicks hatched

Carrier x Expressor = HUGE double dose Carnations

Carrier x Non-Carrier = Single comb

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?

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.

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!!

I think that we may never get rid of the gene completely as there will be no way of knowing who has one copy of the defective gene in their little gene pairs.....but then again I am not a chicken scientist, so I could be way off base and maybe there is a way to single it out and eliminate it.

Very interesting reading! If you were to keep the one showing the recessive trait I would think you could test by breeding unknowns to the one with the recessive trait. If ANY of the offspring show the recessive trait you know that the unknown breeder is a carrier. Right? It would be a lot of work though as you would have to cull all offspring from the test because you know at best, they are carriers.​
