It makes sense that feeding the two nutrients separately may allow the frog to absorb them more efficiently. But I believe it takes both calcium and vitamin in order for the frog to process those nutrients, so feeding them together also makes sense. Feeding the two nutrients separately may not allow the frog to process it then, at least not until the other nutrient is applied.

No matter what, I believe either way would work just fine.
