All info that I have read sad that 25C is beter for incubating cause youngs (C, calyptratus) r stornger ,healthier and better. But this info on E zine chameleons is confusing me.
I wont ,wish and hoppe my chamelons r gonna come out after 180 day on 25 C.
Is that realistic or ill have to eate til 250 so days????
What r yor expirience with C calyptratus?
Thanks

The amount of time required for egg development varied greatly between the three groups. Eggs hatched between 10/11/06 and 3/21/07, anywhere from 170 to 271 days after being laid, with the warmer temperature producing the shortest incubation time and the coolest temperature, the longest. At 29°C eggs required an average of 185 days to hatch. At 26.5°C they averaged 219 days and 252 days at 24.5°C. A simple analysis of variance (ANOVA) test confirmed that incubation time was significantly different between the three groups (F=26.6, P<.05). A Tukey's Test verified that length of incubation was significantly different for all three groups.
Increased incubation period may have some negative consequences in a natural environment. Veiled Chameleons bury each clutch of eggs under damp sand or soil at a single location (Schmidt 1994). The longer eggs remain in the nest the longer they would be subject to disturbance, predation, changes in weather, and microorganisms such as fungus. Disruption of the eggs is likely to result in mortality. Once the eggs harden after being laid, turning them will cause the embryos to become disconnected from the inner shell surface and die, a fate comparable to placental abruption in mammals (Deeming 2004). Lengthening the incubation period allows more time for outside factors to interfere with the nest causing survival rates to decrease.
It was noted that the chameleons that hatched in from eggs in the 29°C incubation were much more active, immediately post hatching, than hatchlings from either the 26.5°C or 24.5°C temperatures. In addition, the individuals from the higher temperature had a greater appetite immediately after hatching than those of the other two groups. Hatchlings from the warmest temperature began consuming crickets within hours of hatching, whereas the others started to eat after 12-24 hours. This may indicate that higher incubation temperature results increased metabolism at the time of hatching. However, this was not tested by any objective means.
