No just lay it on the sand and make sure no water is in the egg. Some eggs are transparent enough to be able to watch the stages. I dont know why some are more transparent than others. If you have an excess of that fuzzy stuff on the casing on the outside you might want to (carefully) trim some of that off. If it's only a little bit - no worries. I just hate seeing them get caught up in that junk - they are such a pain to remove.
