If a female tortoise doesn’t find a mate and get fertilized, her eggs won’t hatch, like a chicken or duck. Well, it depends on what you’re trying to accomplish. If you want to get rid of the tortoises altogether, you can simply remove them from their habitat.
However, this is not an easy task, and it’s not something that can be done overnight. So, if you have the means to do so, then you should do it. But if not, don’t worry.

How long does it take a turtle to lay eggs?
Turtles lay their first clutch of eggs about three to six weeks after hatching. The eggs are laid on the underside of the turtle’s shell, and hatch within a few days. Turtles can live up to 20 years in the wild.
What happens after a turtle lays its eggs?
After all eggs have been laid, the female can spend several hours covering up the hole and then may spend the rest of the night under cover near the nesting site or make the journey back to her home range that very night. The eggs will take approximately 2 to 3 months to hatch.
How long is a turtle pregnant?
Incubation time is variable as a result of egg development and hatching. Incubation for the majority of turtles is between 45 and 90 days, with a median of 45 days. The incubating period is influenced by the species of turtle and the temperature of the incubator. Eggs incubated at 37°C or higher are more likely to hatch than eggs at lower temperatures.
In general, hatch rates are higher in warm-blooded species, such as turtles and tortoises, and lower in cold-breathing species (e.g., birds and mammals). The hatch rate of eggshells is dependent on the type of shell used. Shells made of calcium carbonate (CaCO 3 ) are the most common, followed by shells of silica (SiO 2 ) and polyethylene (PE) (Fig. 1).
Eggs of both types of shells hatch at the same rate, but eggs of PE shells have a higher probability of survival and hatch more quickly than those of other shells.

Do turtles eat their eggs?
Female turtles in the wild lay their eggs and leave. They don’t give any care to their hatchlings. Female turtles don’t have any instincts that would tell them not to eat their own eggs. Pet turtles will eat their eggs if they are a food source.
In captivity, however, it’s not uncommon for a female turtle to give birth to a clutch of eggs, which she then eats. This is called “egg-laying behavior” and is a sign that the turtle is ready to raise her young. If you see this behavior in a pet turtle, you can be sure that she is pregnant.
Can turtles change gender?
Recent studies show that polychlorinated biphenyl compounds, a class of pollutants that can act like estrogens, are able to reverse the effects of estradiol on the hypothalamic-pituitary-gonadal. In this study, we investigated the effect of PCBs on gonadotropin-releasing hormone (GnRH) and luteinizing-hormone (LH) secretion in ovariectomized (OVX) rats. OVX rats were exposed to high doses of PCBs (0.1, 0.5 and 1.0 mg/kg body weight/day) for 6 weeks.
The levels of GnRH and LH were measured in the serum of the rats at the end of each treatment period. We found that exposure to the highest dose (1.2 mg per kg body wt) resulted in a significant increase in LH secretion and a decrease in GnRHa secretion. These results suggest that PCB exposure may have a direct effect on LH release.
What happens if a turtle lays eggs in water?
If the turtle egg is submerged, the hatchling inside will die. It depends on the species of turtle and the time of year it is hatched. In general, hatchlings will be ready to leave the nest by the end of the first week of April.
However, some species, such as the American alligator, may not hatch until the second week in April, while others, like the red-footed booby, will hatch at any time during the year.
