Update; I've been seeing eggs in the pool, and this morning I believe that they have hatched and the tadpoles are in the stage where they stay attached to a surface (in this case, the side of the pool), until they develop further and begin swimming. Now all I need (aside from an entire set up if I'm raising the tadpoles myself) is an answer regarding whether my idea of taking some of the froglets from the kiddie pool is a viable one, or if I should remove the 3-5 tadpoles I want and raise them in a tank.
