If the outside temps are around 80 degrees or above, that means that in an un-air-conditioned carrier truck the eggs could reach incubation temps inside the box. If you have a doubt AT ALL about the eggs, put them in and don't turn them for the first 24 hours. Make sure that they are stored in the incubator the same way you would store them outside the incubator- pointy end down. The point of 'settling' eggs is to allow the air cell to settle into place at the large end of the egg and to allow the chalaza (the spiral tendons holding the yolk suspended in the white) to relax/uncoil as shipping stresses them badly. It has very little to do with anything else unless your eggs have been refrigerated. People allow refrigerated eggs to sit so that they are not shocked by the change in temp from 45 degrees to 99 degrees... but shipped eggs should not have this problem, and can be put straight in without turning.
thank you so much. that's what i was needing to know. hopefully my next hatch will be better if i do this. last hatch was 4 out of 33eggs and i think the heat during transport combined with letting them rest in house, had a great deal to do with it.
