I live a couple of hours away from my uni (so have to be pretty organised with meetings and so on), and have had similar issues with getting responses from my 2nd supervisor. He just hates email and is a bit disorganised, so doesn't tend to reply to emails, and tells everyone just to drop in to see him, which really doesn't work for me being so far away. (But then when I do eventually get to see him he's really, really helpful, so it's worth it!) I've got into the habit of endlessly pestering him, which feels awkward to me but he doesn't seem to mind. It's really infuriating to have to keep pestering him for something so basic, but I've come to accept to some extent that's just his style.
I'd say give it another day so it's two weeks since you first got in touch - that's a perfectly reasonable amount of time within which to at least expect a response. Then as the others have said, ask for initial feedback by a certain date/a supervision by skype or however you arrange it. Give (or even make up) a reason for asking for it by this time if you feel awkward being pushy about this, such as needing to make plans for future research or needing to arrange it around your other work or something. Good luck!
