Should I keep my hoothoot?

I wouldn't worry too much about natures and EVs in game though, unless you were training it for the Battle Frontier.

I have never used a hoothoot, but whenever I play a pokemon game I always use a zubat. It is really hard to train, due to its sucky moves, but once it learns wing attack it gets pretty ok.

My thoughs exactly!
