The following illustrations represent most but not all of the common comb varieties. I would have put more on here, but I was having far too much fun creating the illustrations and if I didn't stop, it could have been a week before I was ready to post!
The Single Comb is probably the most common comb type, found on many breeds around the world, which should come as no surprise as the original ancestor of the chicken, gallus gallus had this comb.
(Edward Neale - Gallus Gallus)
Breeds sporting this impressive, multi-pointed crown include the Ancona, Andalusian, Australorp, Barnevelder, Belgian D'Uccle, Campine, Catalana, Cochin, Delaware, Dorking, Dutch, Faverolles, Egyptian Fayoumi, Holland, Java, Jersey Giant, Lakenvelder, Langshan, Leghorn, Marans, Minorca, Modern Game, Naked Neck, New Hampshire, Old English Game, Orpington, Phoenix, Plymouth Rock, Rhode Island, Sussex and Welsummer.
The Sicilian Buttercup is known for this double-sided, multi-pointed comb.
And now for my favorite...
AKA: Bat Comb!
The V-Comb... Not just for bats any more! This comb is worn by the Appenzeller, Crevecoeur, Houdan, La Fleche, Marvel (just kidding), Polish (Poland) and Sultan.
Combs not represented in this post are the Strawberry (worn by the Maylay) and Cushion (worn by the Chantecler). Perhaps I'll add them later if I get time to do illustrations for them.
So tell us - - how many comb styles are represented in your coop?
