If it doesn't you will have to give it some more frogs or lizards and try again at a later time. Some neonates will switch over to pinkies on their own at 6-9 months of age. Ground and viper boas are the best pinkie starters. Males have very large hooks as spurs, while females have no spurs at all. A 4-6 week cooldown is recommended to stimulate breeding activity.
Candoia breeding is relatively easy.
I use multiple males to insure breeding success males need tp stimulate one another to court and copulate with a female. This is similar to ball python group breedings. The more males you have the better your success rate will be. Male Candoia are usually half the size of females, So you can place a group of animals in a 3 foot cage. When animals pair up , you can then move them to their own enclosures for weeks of copulation.
