Well first of all you kind of need a male snake to go with that female snake. Dr. Del's snake is just an "odd ball" who probably at one time was bred and didn't pass all the eggs on out.

I know female ball pythons should be at least 1500grams in weight and be of 3 years old. More weight is better.

As for boa's & hoggies I'm not sure as I'm still learning stuff about both of them. I do know boa's do not lay eggs, but do give birth to live young like a dog or cat would do.
If your snake has never been in with a opposite sex of snake, then you are in the clear.
