Birds at the feeder

Not that they are eating. The top photo is a finch sitting on top of 'finch food'. Bought it as a block that hangs by itself. First rain did away with that, it just loosened up and fell to the ground. I then put the block in this feeder, it is still in the feeder, no birds even want it. It has thistle in it. Hang the thistle sock up and they eat it all in about 3 days. Not sure what is wrong with this feed.

This is one of my numerous Eastern Bluebirds, she is just using the feeder as a perch. She is looking for insects in the grass.
