Guys, I need some help with a few questions and there seems to be a dirge of info on this new gen so far, so I wanted to see if any of you guys can help me out.

1. Is there a way to breed for specific natures? Or do I just have to wait for one to show up of the right type?
2. Will a Male Pokemon and a Ditto be able to make a female pokemon egg?
3. Where do I go after I beat the Elite 4 to find some of the other legendaries (like the birds, and Zyguarde).
4. How do friend safaris work?

Apologies for my being terrible and not knowing this stuff. If its any consolation I've spent the last 2 days just feeding the wonder trade all the Elemental Fang Tyrunts I can make.
