Alternately, it is thought that a cock (yolkless) egg would give birth to a cockatrice, as they were traditionally thought to be laid by roosters (due to their lack of a yolk). This could supposedly be prevented by tossing the yolkless egg over the family house, landing on the other side of the house, without allowing the egg to hit the house.
The cockatrice, similar to the basilisk, has the ability to either turn people into stone (in a similar fashion to a gorgon) or kill them directly either by looking at them, touching them, or breathing on them. Similarly to a basilisk, the weasel is the only animal immune to the glance of a cockatrice. Cockatrices die if they hear the crowing of a rooster, or if they see their own reflection.
