Very sandy sites, especially those without plant roots to bind the sand together, are often not favoured. This means they can fertilize the eggs even if they have long since had contact with a male.
Add plenty of dark leafy greens, vegetables and their usual feed. Those species which produce softer shelled eggs are much more critical in this respect than those which produce hard-shelled eggs.
Any open wounds should be treated immediately and the animals separated. Below it, use a heating lamp.

Are you interested in tortoises? The incubation temperature is especially critical.
How to Know if your Tortoise is Pregnant

Another way to tell is to ask your veterinary surgeon to X-ray a tortoise you suspect may be pregnant – although this is really only justified in ”problem” cases.
Every year the Tortoise Trust receives a large number of queries concerning eggs and hatchlings. If any doubt that the female is pregnant or not, we suggest taking the tortoise to a vet and getting an x-ray done. One single shot of oxytocin is usually enough to make the tortoise lay within a couple of hours or bringing her horefield. This method will normally prompt laying within a couple of weeks. The first thing to know about tortoise reproduction and pregnancy is that these reptiles reach sexual maturity at around years of age when healthy.
