How do you repair and paint an outdoor resin bird bath?

Go to the automotive section of your local Wal-Mart and get some Bondo (fiberglass resin) for small repairs, or Bondo Glass (fiberglass threads and resin). You can adhere pieces like completing a puzzle with the plain resin or fill in large holes with the threads and resin. I also suggest fiberglass mat if you need to completely recreate a piece.
