I would never feed a hot dog to a bird, it is filled with salt and preservatives, in fact we as humans should not be eating them either, you know what they say, "that if you ever go to where they make the things you will never eat another one in your life" it has other things in it that you wouldn't think belongs in food meant for human consumption.
My fids especially Josey eats chicken, turkey, lean pork cuts, deer and other wild animals that we eat and she has eggs from time to time.
