[tufftie]

There are two solutions to this; firstly you can by fat feeders with guards which stop big birds getting any. Secondly if you make your own fat mix you can make a fat feeder very easily. Get a very large drill bit ans drill several holes around a lower arm sized log. Attach this to some round pieces of wood (top and bottom) of the log, they need to be a fair bit wider than the log. Then run some widish gage chicken wire around the feeder fixing it to the outside of the round top and bottom. Attach an eye and chain to the top, you have to devise little catches for the top fixing s that you can get into the feeder, fill in the holes with fat and away you go. Sounds more complicated than it really is.
