Red-foot eggs are temperature sex dependent, incubation temperatures above 88 degrees F (31 degrees C) will produce females, and temperatures below 82 degrees F (28 degrees C) will produce males (Renquist, 1994). High temperatures however, can cause lower hatch rates and higher rates of deformed hatchlings. The ideal incubation temperature, if mixed-sex offspring are desired, is 84 degrees F (29 degrees C). Incubation periods range from 105 to 202 days, with an average of 150 days (Paull, 1995). After pipping, the baby tortoises will often spend a few days in their shell absorbing the yolk. Often hatchling tortoises will emerge with some yolk sac still present, cleanse the yolk sac with a mild disinfectant such as betadine and keep the hatchling on moist substrate until the yolk is absorbed (Renquist, 1994). Hatchling tortoises can be housed inside in aquariums on a substrate of peat moss and sand, and have the same temperature and lighting requirements as the adults. Make sure to provide areas of high humidity and a shallow water dish at all times, hatchling red-foots are very susceptible to dehydration. |
