Socialize. Get the dog used to living in your environment. Don't go overboard with obedience until it gets more mature.
Do you have a place to run it? Do you have birds? If not, you'll need a pro.
Regarding gunshyness, I've seen people screw up their dogs doing it the wrong way. The right way to is the get the dog obsessed with birds and then start firing a starter pistol. What does gunfire have to do with feeding? Nothing! Gunfire means birds and your dog should LOVE birds!
