You need to patent that thing. I love picking on it, because you hatched what, 75% of shipped eggs in it? Those were awesome results. It reminded me of me, butt ugly, but gets the job done

Well, 80% but who's counting.

I let them rest 24 hrs and go ahead and set them you don't know when they were laid unless the eggs are dated . I had blue eggs shipped 700 miles got 20 and 19 were fertile 11 hatched not as good as sidewing but not to bad. good luck with the hatch
11 out of 20 is great for shipped eggs too.

Shipped eggs with detached air cells is recommended to let them sit up right and hold off on turning. This is my belief: if they are upright there is less chance of the embryo sticking to any side and the first 3-4 days there isn't a whole lot of development to stick anywhere. I think it's most important once they start developing (day 4/5) to when they have developed into an actual chick (day 13/14). If you candle an egg that is being turned upright in an automatic turner it looks a lot different than a candled egg that is being turned. You can really see and experience the "why" we turn during development. With the egg laying on it's side it appears (until the embryo develops into the chick and not just veins and eyeballs) that the chick is only developing on one side. When you turn the egg the development turns so that it resufaces on the side of the egg that is facing up. I found the differences interesting and a bit fascinating when I did my first manuel turning. I question wether eggs stored upright in cartons need to be turned as well. Next spring I plan to experiment with that as well. I want to collect and store x number w/o turning and an equal number with turning and see if there is a big diference in the amount that start to develop.
Very interesting read about turning eggs here: http://dev.biologists.org/content/5/3/293.full.pdf

"Consideration of the arrangement of the egg contents suggests that a particularly critical time for turning the eggs might be the latter part of the first week of incubation. At this time a large area of chorion lies close to the shell membranes and the layer of albumen between the two has been greatly reduced by a loss of fluid from the albumen to the yolk. Abnormal adhesions between the chorion and shell membranes, therefore, seem a possibility at this stage unless the shell and its membranes are periodically moved relative to the egg contents, i.e. unless the eggs are turned. "

I would still rather risk the detached cell eggs turning after two days to give the whole or attached eggs the best possible chance of hatching. I wonder why they didn't do a day 1-3 group? I have heard the embryo picks up nutrients from the egg as it sinks from one side to the other early on, but that doesn't make complete sense to me since it should be fed by the yolk.

I think in light of all of that I would let them sit upright for 2 days and then start to turn. But that's just me.
