I did a search and cannot decide if it is safe. We have a year old gingerbread kit that includes prebaked slabs. They are hard and dry with no sign of spoilage. Can I give this to my chickens? I am thinking it would be really cool to ice and decorate with suet and birdseed, but I would have to put it up out of reach of the dogs. Dogs + birdseed laden fat = stinky tarry yard disaster and dog with abdominal pain! Any other chicken edible stuff that could be used to decorate?
