OK, so our team regularly adds Twitter and Blog feeds to websites. Often we get aksed to add a Facebook feed... thing is, Facebook is not really a "feed" as it's made up of posts and info from you and other users. So to add the Facebook "stream" to your site, what you need to do is add a customised view of the "Like Box" social plugin.
To do this, follow the instructions on this page:

Happy coding!
