I had a white and blue parakeet I called snowball...Make sure you have clean water at least once a day!! Birds can get very sick if they have dirty water and many birds like to "dip" their food in their water. It really helps if you get textured perches so their nails aren't too sharp. Like everyone else said, hold them a LOT and have different people hold it so it doesn't get used to one person. Put LOTS of toys in the cage because if they get bored they get destructive and can pull out their own feathers if they feel neglected.
REALLY watch out for your yorkies!! Mine "hunt" my bird all the time and we have to put up the baby gates if I take her out. (I have a cockatiel now)
HAVE FUN!!!!
