I'm a little worried... Anyone have experience or knowledge with postal policies on heat and live animals? I ordered a batch of chicks months ago, thinking Sept would have decent temps for delivery. Generally cooler, but not cold. Turns out, we ended up having one of the hottest days of the summer both here and where they will be coming from. We've had heat index warnings and indices of 100 +. To add to my worry...They were picked up by the USPS and the last tracking info I have shows that they made it to a distribution center in Mansfield, Ohio last night at 6 pm. But no further updates provided. I know they can go 72 hrs without food or water. But I'm worried about them inside a delivery truck, baking in the heat.
