i didn't quite understand what you meant? were you saying that if you incubate yours that they eat....upside down? or that they travel down?
when i incubate they dont hatch on their own at the same time amount and conditions. as the tub i had them in was very moist with bead if condensation but not wet near clutch....
and when hanging the seemed to eat apart their clutch and came out the tip of the bottom, just theorizing,...as to why they weren't hatching well or surviving when incubating,..
