I am on day 19 and I am trying to follow the sticky on humidity and lockdown in this forum. It instructs you to wait until you see an internal pip before you stop turning and then once you see external pips you increase the humidity and keep the bator closed. Now I have had successful hatches before by following the rule of turning until 18 and then lockdown but I have always had one or two that are fully formed and yet don't hatch. Has anybody else tried this method?? What is your feedback? My eggs are all still viable and moving and the air cell has started to dip on one side but no internal pips yet any advice????
