If you've got the BlackBerry Beta Zone app downloaded to your BlackBerry 10 device, you might want to open it up and see if you have a Facebook for BlackBerry 10 beta available to you. A new release has now appeared and while the change log for it appears to be short, summing it up to just bug fixes and improvements to the news feed, the news feed is one of the biggest issues on with the app right now. Again, this is only in the Beta Zone app so you'll have to grab it from there assuming it's available to you.
