What have you observed that led to your conclusion that contact with a substrate is better?I am in the process of writing a narrative documenting every step and misstep I've taken with these animals. One thing I will say now is I do NOT recommend a SIM style of incubator. From what I have observed, the eggs needs to be in contact with a damp medium such as a vermiculite/sphagnum mix (what I have used in the past and will continue to use in the future).
WOWIE-ZOWIE!!!!Fast forward to 2019: the smaller of my two breeding C.m.o's gifted me with eight eggs today and the larger of the two seems like she's ready to pop as well. No more messing with experimental incubation techniques for me! The eggs are incubating at a temp of 82 F in a medium of vermiculite, pulverized sphagnum and water. This has worked great in the past, fingers crossed it will work just as well now. BTW, eight eggs is a large clutch.View attachment 279324
