Sometimes you can find a non-profit organization that will sponser Fae. They might be able to help you with the cost of spaying her. Even ask the vet. My vet fixes animals at a low cost for special circumstances. All of my animals are fixed, but I believe that if they aren't fixed, they tend to run away more. It is really important for you to get Fae spayed. It's not healthy for her to keep getting pregnant.

Dogs chew when they are bored or want attention. Perhaps if you provide her with some good chewtoys, she'll quit chewing so much. How old is Fae?
