Is this comb common in a Wyandotte rooster?

[Coffetym]

We have silver laced Wyandottes with 2 roosters in the mix. They are all right around 17 weeks old. According to everything I found in studying the breed, the roosters have rose combs. One of our roosters has the classic comb & I was wondering if this is common or not.
Below is pics of the rooster with the non rose comb.
Thank you for any feedback & info.

A single comb is caused by a recessive gene. This is common in hatchery Wyandottes.

Thank you but I hate to hear this because this is my roo & my wife keeps telling me that he isn’t normal so she’ll be glad to remind me of his abnormalities.
