If regular fencing means chain-link, then it is fine for protection against dog, but weasels and minks (you almost certainly have them but don't know it- I'm in a pretty big city and my neighbors lost 12 birds in one night to a mink) can get in, so it's got to be closed at night if you have holes less than 1"- and not chicken wire. Raccoons (worst city predator out there) can get into chicken wire.
Please at least go read a quick article about predator-proofing. Here's another about things you'll want in your coop.
