Glue a old pot saucer on the bottom (also drill a few small drainage holes in it) Then they can throw the seeds about in that and not on the ground. I also protect mine from the pidgeons as they tend to eat all the seeds and break off the saucer.
We did this with one of our feeders but now the pigeons have learnt to perch right on the edge of it and they're so greedy. I like your idea of mesh around the outside though - I'll try that next.
