Well, I've been training Peep with a clicker. It's working rather well.
Peep is generally pretty tame unless he's in the same room that Salty is. If Salty is in his cage, and Peep is not with him, Peep will frantically start trying to get to him.
I would love to put a picture of my lovely birdies up here, but for some reason I can't upload. It says that the direcotry is full.
