I have what I think is a "pretty decent" rooster. A buddy of mine is wanting to show Chickens and I offered to let them show my boy. That way they can learn how to condition, prepare and judge the bird without paying slot of money out for a "top" bird. He has a small side Sprig...How much will that hurt him? Also, is that enough reason to not breed him?
Thanks Rooster

Severity of side sprigs can sometimes depend on the judge. We have a hen we have shown 5 times and the last time the judge noticed the slightest bump of a side sprig and disqualified her. The other 4 times she placed 1st or 2nd. The disappointing part was that it was my son's entry in the Jr show. He had helped with washing etc and was disappointed when he went to see what ribbon he got this time. I would not want the same thing to happen with your friends showing at their first show. I wouldn't risk it if the sprig is visible at all. Maybe post a picture if you can and see what people think. I will see if I can get a picture of the comb on our hen that was dq'd for comparison.

I would always get rid of cockerals that had side sprigs, try to keep them out of the breeding pens. But according to the above article. you can test mate the birds by breeding them to clean comb birds. I have used pullets with side sprigs and breed them to clean comb cocks and received a large percentage of clean comb females and males free of side sprigs. That will also be determined by how large or small the gene pool is in your flock.
So basically you can use a side sprig breeder with a clean comb breeder and get clean comb birds but keep documentation. Because you are dealing with autosomal dominant genes that need to compliment each other.

The only way the side sprigs will show up in the young ones is if the hens are carrying a copy of one of the side sprig genes.

The only way the side sprigs will show up in the young ones is if the hens are carrying a copy of one of the side sprig genes. After much reading here and elsewhere....with my limited knowledge of genetics...which you just went WAY past!! LOL It is much like a single recessive gene in that you need 2 genes for it to show, the difference being that you need 2 different genes rather than 2 copies of the one? SO I think he is a useful bird in that I could use him to test breed to prove that my breeding hens do or do not carry the complimentary genes that cause the side sprigs. Then I could remove the hens that carry the genes, thus eliminating the trait from my breeding program. Breading clean comb Hens to clean Combed cocks would not help as that only proves that one of the birds does not carry the gene. I don't believe I would want to keep any of his offspring as they will all posses at least half of the genotype for side sprigs. Am I on the right track here?

Am I right that seeing as we are dealing with a combination of genes rather than a doubling of a single gene, that I would only get 25% showing with 100% hetero rather than the 50% showing & 100% hetero with a single recessive?
Please correct my terminology if I am saying anything wrong...I just recently learned that using the term "rooster" when referring to a cock bird is bad....lol!

Statistically there are a lot of birds out there carrying one of the side sprig gene. Like some breeders say they seem to show up when you out cross. So for years there is a line that is carrying one of the autosomal dominant side sprig gene that hasn't made an appearance for generations. And then one day you cross you line into another line that has been carrying the other autosomal dominant side sprig genes and then they start showing up in your birds. So there you go. Basically you want to try to keep these genes separate so they don't compliment each other. So there is always a chance that a nice pretty clean comb bird is hiding one of the side sprig gene.
