Angulate Tortoise Eggs & incubation
Angulate tortoise (Chersina angulata) female digging a nest Female vs male See the male vs female Angulate tortoise (Chersina angulata) page for info and photos on how to differentiate the sexes (sexing). Courtship & breeding See the Angulate breeding page. Egg laying Angulate tortoise females usually lay only one large egg. Occasionally, two eggs may be deposited. In these cases, the second egg could actually be a retained egg from a previous clutch. Older, more mature females can lay up to 6-7 clutches per year. Younger females may only lay 1-2 clutches.
Freshly laid Angulate tortoise egg (after it was dug up) Incubation of eggs Incubation conditions for Angulate tortoise eggs vary somewhat among breeders. Here are a few examples of published incubation temperatures and humidity levels. For more details, please read the original publications. 1.) Thomas Bauer (Turtles, Proceedings: International Turtle & Tortoise Symposium Vienna 2002, 2006) Egg box is filled with slightly damp, sterilized soil. Eggs are placed in shallow depressions, but not buried. Eggs are incubated at 27-30 °C (80.6-86 °F) with 85% humidity. Incubation lasts 110-125 days. 2.) Jürgen & Susanne Fleck (Elaphe, 3/2001) Eggs are incubated on vermiculite at 30 °C (86 °F) with 80-90% humidity. Incubation lasts 95-127 days. 3.) A. C. Highfield (Practical Encyclopedia of Keeping and Breeding Tortoises and Freshwater Turtles, 1996) Eggs are incubated at 30 °C (86 °F) with 60-65% humidity. Incubation lasts 90-100 days. 4.) Milos Junek (euzelva.cz) Eggs are incubated at 30.5-31 °C (86.9-87.8 °F) with 95-97% humidity in a water incubator. Reported incubation lasted 101 days. 5.) Gunther Koehler (Incubation of reptile eggs, 2004) Eggs are incubated at 27-30 °C (80.6-86 °F). Incubation lasts 95-127 days. 6.) Sven Wlach (Schildkröten im Fokus, 2/2008) Eggs are incubated at 31 °C (87.8 °F) for 20 hours a day and at 25 °C (77 °F) or below for the rest of the day. Humidity is kept above 50%. Incubation lasts about 120 days.
Angulate tortoise nest. The female abandoned it as not acceptable. Probably because she hit a heavy root at the bottom of the nest.

Angulate female. Amazing, how such a large egg fits through such a tiny opening. In both male and female Angulate tortoises, the bony gap for the tail (and egg laying) is very small. Inbubators See the Star tortoise eggs & incubation page for info on incubators. Incubation substrates See the Star tortoise eggs & incubation page for incubation medium info.
