Cockatrice lairs are often littered with fragments of statuary from past victims-although these are as likely to be remnants of frogs, lizards, and insects as people. Curiously, weasels and ferrets, who infiltrate cockatrice lairs to steal their eggs, are immune to the creatures' petrifying bites. For unknown reasons, cockatrices are both terrified of and enraged by conventional roosters, and they are equally likely to flee or attack when confronted by one.
