Our incubator is a sytrofoam box that we fit somewhere in our snake room. The temps fluctuate between 80 to 84 which is reasonable. Of the babies we hatched one clutch was good, the other had 4/13 babes kinked and the third 5/12 kinked. I'm not sure if it's temps or what? We have hatched out some lizards from the same incubator with no problems.
