Advice for hatching shipped eggs?

[PioneerChicks]

I'd recommend setting the eggs the minute they arrive.
It's hot everywhere and the eggs could have already started to develop.

After traveling in a hot postal truck, the chances of the eggs already starting to develop is great. Letting them 'rest' in an air conditioned environment will kill the developing embryos. It would be best to set the eggs in the incubator, that has been running and has stable temperature, with the turner, 'turned off' for the purposes of resting the eggs.

Living in South Texas, this is the only way to handle shipped eggs due to the heat, even spring can reach into the 90's, in an enclosed postal trailer, the temps can easily reach 110° or 140°F or higher. Even if it only reaches 90°F, inside the trailer for 3 to 4 days (priority mail) while being shipped those eggs will have started to develop.

Woah, that's crazy! It is starting to cool down, but I'll put them right into the incubator after candling. Thank you both!
