There is one thing I do with my eggs - egg vases. These are last years wild jonquils which are now up but have yet to open. You can also use them for seedling starters. Just rinse and fill with peat moss and seeds and keep wet till they sprout. Also, prick a hole in the bottom of the egg so you won't get dampening off (the sprouts will shrivel up and die from too much water). Leave them sitting in the carton for easier handling. Carefully crush shell for planting; good source of calcium for the plant.
