Messy, Wasteful Goldfinches

In my last thread about goldfinches here I was complaining about the distinct lack of them. Now I get so many that I simply can't fill the sunflower heart feeders fast enough. Yesterday, I counted seven on the feeders and more in the trees waiting to take their turn. 

My problem however is that after watching these little blighters closely for  a few days, I've noticed that they are very wasteful - often throwing 3 to 4 perfectly good seeds to one side before actually grinding on one. I know that they usually split the seed when they chew (is chew the right word?) and theres waste as a result of that, but they are literally throwing a lot of seeds to one side before they get one they want to bite on.

The Wood Pigeons usually come and hoover them up, but I think even they are sick of soggy sunflower hearts by now.  I'm also worried that too much waste around on the ground will attract vermin and I don't think my Neighbours would appreciate seeing the larger furry mammals running around the garden.

Does anyone have any tips?

I have thought about grinding the Sunflower hearts up a bit in a chopper\blender as I think its the larger ones that are getting thrown to the side. Anyone had to do this?

I love having the Goldies in the garden but the mess and waste is bugging me a bit. 

By the way, got the first baby Goldies in the garden yesterday and today. I did get some photos too :) I'll post some once I've cropped them as they are very small in the frame.

Thanks for any responses people.
