Well that was a lot of interesting reading down below...
There was a lot of theory, a bunch of field observations, and very little actually discussing how go about applying any of this to our captive husbandry. Thats what I want to do.
Last year I moved from the north east (humid as a sauna) to Colorado (bone dry) and I had to adapt my husbandry in some very significant ways. I keep mostly desert species (ant hill pythons, sthenodactylus geckos, cal kings, etc) and when I lived in an area with high humidity I was deceived into believing that they liked it as dry as possible. Turns out that the ambient humidity was simply more than adequate for them. All of my animals did great with aspen and a water bowl. I would use humidity chambers for gravid females, "hibernating" snakes (more on this later), and a few humidity loving sp. (black milks).
For the first three years that I kept a large colony of anthill pythons I only saw one drink once.
However this past year in CO, I had more shedding issues that ever before, a tough time with incubation (first time ever that I got several full term dead in egg clutches), several snakes that did not bounce back from breeding efforts quite as vigorously as usual, a colony of geckos that mysteriously stopped breeding (I had never watered them in over a year back east) and baby snakes, especially the little anthills, suffering from constipation.
All of a sudden I see the adult anthills drinking every once in a while.
Hmmm???
Well it didn't take me too long to realize that some changes were in order.
The biggest changes that I made was going from a thin layer of aspen to a thick layer of cypress as a substrate. I started spraying and STIRRING the bedding once a week..ish. With my kings I started using boards as hides. The large board covers the length of the tub but only half the width. The large surface area allows some really nice humid pockets to form if you spray under it every once in a while. This is MUCH easier to manage than having 25 adult snakes, each with a "humidity chamber" that needs to be maintained.
I started spraying the geckos every few days and moistened the sand under one hide. They come running out and lick the drops. Hopefully I will start getting eggs again soon.
With hatchlings, I also switched to cypress, and with the hatchling anthills I evened switched to using covered tubs to increase ambient humidity.
The adult anthills are the only ones still on aspen.
So lets put some numbers to it. Humidity on the east coast was rarely below 75% but in CO it is usually closer to 50% or less with the heat on in the house during winter. I havn't actually measured the humidity in different parts of the cages but I think I am going to try. I will report back on this.
anyone else care to chime in about how you manage humidity in your collection, where you live, and your results... I'd love to hear about it...
Cheers
