Ok.. Ive got a few eggs in the incubator that arent any good... Is there any way to blow them out to still be able to use the shells for crafts?? Im wanting to give them to my daughters preschool class if I can.. OR.. is this going to be too gross?? They have been in the incubator for 15 days and not showing any signs of growth.. I dont want to have any rotten, smelly, yucky stuff coming out.. and id rather not use my mouth to do any blowing.. I can use a big syringe... Thanks..
