almost all eggs are pointed small end down like they are tilting.. does that mean anything? They weren't like that yesterday. It is the end of day 19..

not sure as I have always kept mine big side up to hatch in a carton???? Maybe they are just heavy on one side because the chick is getting into postion to pip....
