silkie with a comb ?!?

[klf73]

I am new to silkies, but from what I read this sounds odd. I was inspecting my 3-4 week old bearded silkies and saw something "poking" out of it's forehead. It has a comb, small, pointy, but there. This normal? These were eggs I hatched and paid some decent $$ for.
Any info appreciated...

edited to say that since I was asked I will add that < No, this particular silkie was not from chellester

Those are what I call boo boo babies. It happens sometimes a lady I buy silkies from has those hatch out once in a while. She gives those away to a friend of hers who doesn't care if they have single combs or only 4 toes on one foot. So far I've not had any pop up in my silkies yet.

Its a simple recessive trait- but I was surprised by one in this Spring.I gave it to a good home
