Quote: yes ALWAYS point down... the air cell needs to be on top for the chick to develop normally. especially if air cells were damaged during shipping, keeping them imobile for a few days after incubation has started (no more than 3-4 days) will help them heal as much as they can. if you use an auto turner, then you can start turning after a few days. ifyou turn by hand, i'd put them in an egg carton and tilt it 30-45 degrees each way several times a day. if you lay them over, the air cell will never stabilize and can damage developing blood vessels if it moves too much.
if you put the air cell down, it may try to relocate, and a chick trying to hatch at the small end of the egg usually doesn't do so well. just had to rescue a shrink-wrapped upside downer...
it's ok, it is very weak from struggling to hatch for an extra day.
