We got a fruit cake from a neighbor, and none of us care for it. Is it ok to give to the chickens, or is there too much sugar and sweet stuff in it for them? I'm not an expert of fruit cake, but it looks like it is loaded with colorful "stuff" and she said it was a "light" version. (I think she means the type of dough, because it is light in color, not lowfat.) Thanks!
