I feed whole sunflower hearts to mine. The birds bite them into smaller pieces, most of which end up on the lawn. I had wondered about crushing them first, but was afraid that they would go soft and mouldy. Seems like I was right!
I find it pretty essential to clean the feeders regularly. And the birdtable (though I only use that in winter). They get to pick up diseases from visiting birds, which are then easily spread to healthy ones.
