Build-a-Cockatrice (Patreon)

It's time once again to build a creature, this time a cockatrice as suggested by three. The comments get to decide what parts this beast will have, in order of the numbered list. If you're unsure what caruncles are, it's the fleshy bits that chickens and many bird species have on their faces: https://en.wikipedia.org/wiki/Caruncle_(bird_anatomy) 

These prompts are going to be posted on the 15th of the month at 12pm PST until I either get bored or too busy to do them. If the comments are full by the time you get here, suggest another riddle, or another beast I could do a build a creature post with!
