Is it actually a "Facebook Group" that you're looking to show the feed some? If so, no, we don't. Facebook doesn't have an easy way to get a Group feed, and actually have been phasing out groups slowly over the last year. While they aren't being removed completely, they are paring back their features and making sure that Groups are used only for small 'groups' as they should be. They recommend using Facebook Pages for most stuff, which can show the feed from and what Facebook and JFBConnect has a lot more tools for support (like our Page Tab integration).
Hope that explains, even if it may not be what you're looking for.
