Winter Shipping

My Albino Cal King gave me a late clutch (laid the night of 9/28 to 9/29) of a dozen eggs.

Late september lay means late november or december hatching. By the time they have shed twice and fed thrice, it will be well into winter.

As far as selling them and shipping them is concerned, would it be better off for me to just hold them back until spring, or will a 72 hour heat pack be sufficient for small body mass reptiles in the winter?

What worries me is that small body mass means they have less heat to lose and are more likely to have temperature related issues.

I have no experience shipping reptiles, only in receiving them, and never in winter. I have found several good resources on shipping them the correct way, and I just opened a FedEx account to get the process started, but I don't know how small body mass will be effected in a winter shipment.

My primary is to do what is best for the snakes.
My secondary agenda is to let other people provide homes and buy the pinkies.

I appreciate any advice.
Next year, she won't be breeding so late, I aquired her in August, hence the late season copulation.

IMO, it would depend on where they are going & the conditions at the time. I have shipped during the winter, but I have used 1" foam insulation board. Origin and destination temps need to be considered when figuring out which (and how many) heat packs to use, though a cal king can tolerate cooler temps than most boas and pythons. Personally, I am rarely in a hurry to get rid of babies, and I generally hold onto them longer than most...of course, if I start getting too many around here, that may change, lol. The point being that by the time I would be considering releasing a baby hatched Dec 1, it would be at least mid Feb anyway. If you aren't eyeing profit, hold onto them until the conditions are suitable, a couple of extra weeks isn't that big a deal.

Thanks for the input.
I'll keep them through mid march, assuming nothing goes wrong with the clutch.

That also will give me a little more time to evaluate the best one for my little brother down in the bay area (I want him to have a good feeder non nipper) before I start selling them.
