What's up with this comb?

[Cyprus]

I have a 6 week old Japanese Bantam Cockerel. Japs are supposed to have single combs but this guy looks like he started growing a single comb and then it mutated. Any ideas? Both parents have single combs.

I really don't know but I'll be following.

Severe sidespurs??

Kinda looks like it has a rose comb in its ancestry. Otherwise, the comb gene didn't get the right instructions for single comb.
I use to raise BTW Japanese, never saw a comb like yours has developed.

I have a mixed bantam pullet who I’m pretty sure is part Japanese Bantam and she has a similar comb. I thought maybe it was a carnation comb

I have two pullets from this year with the same abnormality. One is rose-comb and one single, both with the same splitting at the end of the comb. They are full sisters from my Silkie mix cockerel and a single combed Marans mix hen. I believe the springs came from the father, and I have considered that it may be the result of the v-comb gene.

Next year they will be going to single combed cockerels, and then the year after I shall breed the cousins together to see if a bird homozygous for the gene/s responsible will possess a full split comb.

Looks at bit like a v-comb and a single comb smushed together. Don't show him; you'll be disqualified. But he sure is a pretty color!

I did work on comb genetics. Silkies do not have V combs. They have what is called a walnut comb, which is a cross of pea and rose. Therefore, they have one Rose copy, one Pea copy and one Single copy.
Being that single is recessive, it is not expressed. When a silkie is croased to a Single comb, most offspring will be pea, some rose and some single with all having a split somewhere. Silkie combs started as a muddle of a lot of things.

I don't intend to show him. He may go into project breeding to try to prove this gene.

Single is recessive so if anything else were present in the parents they would not have single combs.
