today is day 22....you set the 1st....the 2nd is day 1....today is the 24th so it's 22 days....but!! if they ever cooled if you had a heat fluctuation they could be a little behind...make sure they have a good amount of humidity...if you open the end of one of the dark ones you believe is internally pipped and it is you won't hurt it...worst thing is you'll be committed to helping it hatch...but then it'll help you determine the status of the others
