I decorate eggs and someone told me that there are some swan eggs in a shop near here. I had seen the eggs when I was in the shop, which is an antique/pawn shop but thought they were some type of fake eggs because there are no blow holes in them. They are not very heavy and I am wondering if these are indeed swan eggs, what will be on the inside? Also, are swan egg shells thin or thick? I would have to cut out an oval in order to create the decorative egg. Any info you can offer would be very helpful. I also have no idea what to offer for the eggs if there is a possibility that they could be decorated.

Thanks!!
