Gargoyles and cresties.

There are indeed Chahoua and Crested pairings. They look very beautiful but cost just as much if not more than a Chahoua itself.

I'm not 100% sure but the Gargoyle x Crested pairings were not viable and most had defects.

Hybrids are often frowned upon, but if you can tell the difference and if you don't keep adding cresteds to crested x chahoua, (meaning you do chahoua x crested and only breed to chahoua x crested) why does it matter? Just my two cents.

Not like it hasn't happened in the wild. :O
