Not a bro.
When I made a laybox, it was a 31qt Sterilite tub and I lined it with about two inches of moistened sphagnum moss.
Here's a link to my a thread on my first experience with maternal incubation.I don't recall saying that? They can't alter temp through shivering like other pythons but they can leave their eggs to bask and return to brood after their body has warmed up. I have not observed this with my females, obviously, but I have read about it in an article on wild ball pythons. As for humidity, the females can alter the humidity within their coils by tightening or loosening them (I can see and feel light condensation on the female's belly and her eggs when I've peeked in to candle eggs and the rest of the tub is dry) and they can urinate within their coils if there is no moisture available to them. Thankfully, I have not noticed this with either of my females. At least, I don't think that I have. I would think that I would have noticed an odor and I haven't.
Thanks. Today makes Day 52 and 49 for these two clutches so I should have babies in the next few days. I would be surprised if I don't have pips in the older clutch tomorrow.
Last year I did this and my female refused the meal I offered a couple weeks into incubation. Because I had read so many threads that said they wouldn't eat anything during incubation, I assumed that it was to be expected and didn't offer food again until her eggs hatched.
I offered a rat pup to both of my females last week because I had extras and figured I'd just see if they had any interest. One ignored hers but the other wolfed it down without any hesitation. I wish I had thought to offer food earlier on but I was still under the notion that they would just refuse whatever was offered. Another poster here, anatess, is maternally incubating and their female has apparently been eating every 10 days. I suppose it's all according to the female in question. From now on I will offer a small food item at least once every two weeks to my brooding females.
I don't think substrate really matters that much. I just like the look of cypress mulch and it doesn't mold when it gets wet like some other beddings. Both of my females have pushed all of the cypress aside and are laying on the plastic directly over the heat tape. Because they are in tubs, the humidity doesn't drop very low. The lowest reading I've ever gotten in one of my tubs was 60%.
I have only removed a female from her eggs once during this whole process and that was because one of her eggs had rolled out of her coils and I needed to place it back closer to its 'siblings' to make sure it would just tumble out again. With all of the eggs situated together, I put the female back in the tub and she gathered them all back up in her coils with no further incidents. I wouldn't remove a female from her clutch unless I felt it was really necessary. Too much stress could cause them to abandon the clutch.
I know a lot of keepers/breeders routinely weigh their females, but I don't. I'll probably weigh the babies when they hatch and I would also weigh any problem feeders I have to note any weight loss over a period of time, but I've never routinely weighed my snakes.
Thanks for the well wishes, guys! I hope to have babies and baby pics soon!
