Pair or Trio?

[hhw]

For a casual herper new at breeding, would a 1.1 pair or a 1.2 trio be better for breeding stock?

On the one hand, an extra female would mean an increase in chances for success, and for 50% increase in stock you get 100% more offspring, which seems like a pretty good yield.

On the other hand, you'd have twice as many babies to deal with: to house, feed, and sell. This results in more time and resources for the babies itself, and also just in raising the extra female, which may increase the difficult of the project.

So, what would everyone suggest for a first breeding attempt: a pair or a trio?
