The spell you're looking for is "Imperio!"

 

Or a sticking charm. Or a compulsion spell.

 

Ugh. HP magic is overpowered. In any case, the lack of basilisks running around does tell us that it's probably not all that easy for just about anyone to create a basilisk and rampage. The lack of a glut of basilisk venom/parts in the shops of Diagon and Knockturn also drives us to the same conclusion.

 

I realise I'm probably being a bit pedantic here but my first thought when I read the thing about hatching a chicken egg beneath a toad was 'but a toad isn't warm enough to incubate an egg'.

And I was right! A toad would be unable to keep the egg above even room temperature, and the toad may die if heated to chicken incubation temperatures for an extended period of time. In fact a toad would be unable to warm an egg even to the lower temperatures required by most reptiles.

But this is magic and all that is almost completely irrelevant. Carry on.

 

So now I'm feeling this strange pull to have Voldemort raise himself a basilisk to replace the one from CoS, deafen it (suck on that, cocks) and let it loose for some sweet, sweet chaos. I don't think lack of hearing would impair it too much if it could still see and smell.

Credible?

off topic: I fucking hate mobile web browsers.

 

How do you deafen a snake? They don't have ears, they merely feel vibrations in the air.

Edit: Voldemort could create a strange magical disease that only kills cocks. That way he can save his own pet snake. Lel

 

The innuendo is strong in this one.

 

Ahhh. Perhaps the basilisk-cock thing is more purely magical in nature. It doesn't matter what kind of sound the cock makes, if the basilisk can perceive it, it just dies. More in line with Taure's interpretation of magic.

Killing all the cocks would be a horrible thing. There would be no more delicious meet. Only Voldemort could commit such an atrocity.

 

Maybe it's easy to hatch the Basilisk, but not bring it up? I'd imagine taking care of something that can kill you with puppy dog eyes isn't a risk many dark wizards are willing to take. It'd make sense that the rearing part would be difficult. Or maybe the egg has to be hatched on a specific day.

Although, what would happen if the Horcrux-Shade of Tom Riddle from COS looked the Basilisk in the eye? What would happen to Ginny?

 

I like to think that a basilisk is capable of controlling its lethal stare. I don't think it would kill the Heir of Slytherin. It's not outside the realm of possibility that there may be spells in CoS or on the basilisk itself that allow it to recognize the Heir and force it to obey the Heir's commands.

So as long as Riddle had a use for Ginny while he was possessing her, she'd live. We know she was supposed to die eventually.

 

Anyone have the exact quote in either the book or Fantastic Beasts about the egg hatching?

It may be a situation where the toad needs to sit on the egg of its own free will.

 

Then breeding a basilisk really could be that simple, but it wouldn't necessarily be easy.

 

1) It says "hatched". It could just as well mean that egg has to hatch in whatever way, as long as toad is present on top of an egg. It's possible that toad doesn't have to be source of heat.

2) When toad is cold blooded, it doesn't mean they can't be warm, right? I found this:
