I'm keeping an eye on the weather too. As of right now, it's looking like the Gulf Stream will be keeping my area around the low 40's for the middle of next week. If the temperatures are expected to drop below 40, I'll have the breeder hang on to the snakes until such a time as the weather is more accommodating.
The breeder has a pretty modest operation, and told me that the snakes I've purchased are all in the same set of racks. I was planning on keeping them separate from the snakes I already have for a couple months, but saw no reason to keep them away from each other as well. Shipping stress is a new one for me though. What sort of issues can come of that? I'd thought that if the animals arrived uninjured and took their first couple meals without any trouble, that they'd be set except for the quarantine.
