A lady that I am getting eggs from Sat said that she heard the oval eggs are hens and the pointed ones are roo's. She has been experimenting with this for 2 years and has a 98% success rate for having hens. Good luck (I will have to make a note to let Miss Prissy know this as she always has more roo's then hen's) Good luck that would be a great experiment for the board don't ya think. LOL
