making bird food? (1 Viewer)

We have pet rats and feed them a block diet. At the bottom of the bag there is always an abundance of unusable crumble. Certainly there is a way to use this to make bird food? We have all the usual robins, cardinals and sparrows. Living close to woods, we also have woodpeckers (downy and red belly), nut hatches, tufted titmouse. With my grass and garden going to seed we also have lots of goldfinches now.

I'm not sure what 'block diet' is - but if the left over is solid, seedy stuff, could you perhaps melt a block of suet in an old pan, tip the crumb stuff in and let it set in a tube (perhaps a bit of old plastic pipe?) with a string set into it, and then when it sets you can just slide it from the tube and hang it up.
