How many ltt's can you fit on an empty fat feeder?

Sorry - longtailed tits again. They were pretty much the only things around at dusk when I got in (they do make the most of the shortening days).
Parkinson's group christmas lunch today; physio first. I cracked a rib on Monday and it's getting more painful.
I honestly wasn't doing anything stupid and I didn't fall - just stretched over the wooden fence to pick a plastic bag off a branch and CRAACK! 11th rib (floating) - hope it's just cartilage that's broken and it won't take too long to heal!
That's the lot for tonight - just going to make an apple pie for the blipmeet tomorrow - MeeshJ and KenPetch are coming (children's coughs and weather permitting!).
