Suet at this stage is still somewhat soft, but if you melt it and strain it again, you will produce a very hard suet. To make suet cakes, heat suet until it melts. As it cools and thickens, stir in chopped peanuts, sunflower seeds, bird seed mix, or other ingredients your birds will eat. The traditional suet feeder is a small wire cage, which may be placed on the trunk of a tree or suspended from a branch. You can also place suet in a nylon mesh bag.
Some bird feeders have a hopper for seeds, and suet cages on the sides of the hopper.
You can put either raw or prepared suet in these feeders. Soft suet mixtures may be spread on tree trunks or smeared onto pine cones that may be hung. Starlings are particularly fond of suet. Squirrels also love suet. You may be able to slow them down by protecting your feeders with baffles.
