hey, MRosie,
about the light fixtures. I also had one with some curvy parts like one that you showed. I'm not sure what to do with it. My success was taking a used hanging outdoor light fixture, from above the front door, take out the glass, and put a small dish in it. I'll get a picture when I fill it next. It's bad when it rains, the seed gets wet, but otherwise birds seem to like it.
