Fed Ex should be able to put the package in a climate controlled room, especially if you paid for overnight shipping. I would be on the phone with someone at the location until I had it guaranteed they were in an office or something. Especially being live animals, someone there will be willing to help.
Yes, they have it in a climate controlled office. But, I am concerned, because they will be in the box for almost 6 days. These are babies.
