You don't you actually use it to make a spirit cockatrice puch.
Yes. I have bought them there. If they are out of Kindle cards, you can buy Amazon.com cards. They are interchangeable. You can use Kindle cards to buy anything on Amazon and you can use Amazon cards to buy any Kindle books.
The important thing is to carry a mirror shield with you. Otherwise, the cockatrice will quickly lower your combat stats. You can buy a mirror shield from any slayer master, or from the Grand Exchange.
A cockatrice's spirit is to turn others into stone. For example, in my little pony the cockatrice turned twilight and the chicken into stone.
to buy things!!

Yes. eBay is a source that many collector's use to get cards.
Yes
The cockatrice was supposed to come from an egg laid by a cock (i.e. a male chicken) and incubated by a toad
No you can't. You must use your best buy cards at best buy.
The Cockatrice egg is a "bonus" drop from a Cockatrice (level 37 combat), which makes it among regular drops from this creature. It is used in Herblore and Summoning.Herblore: used to create summoning potions.Summoning: used to create Spirit cockatrice pouches to summon Spirit cockatrices.It can`t be incubated at a pet shop.They can also be made from a normal chicken egg by using the Spirit cobra's scroll Ophidian Incubation.Also note that having a Spirit Cockatrice familiar seems to boost the odds of getting the drop of a cockatrice egg while fighting against Cockatrices, and the Spirit Cockatrice will also create one every now and then.
