How Do You Grow Turtle Eggs at Home?

Published in Reptile Care 3 mins read

To "grow" turtle eggs at home, you'll actually be incubating them after they've been laid. You don't make them grow, you facilitate their development. Here's how:

Setting Up the Incubation Environment

You essentially need to replicate the conditions a turtle nest would naturally provide:

  • Choose a Container: An aquarium or plastic container works well.

  • Select a Substrate:

    • Egg Carton Method: Place the eggs in an egg carton. This helps prevent them from rolling around.
    • Sand Method: Use clean, slightly damp sand (about 2 inches deep) to bury the eggs. Vermiculite or perlite, also slightly damp, can also be used. This helps maintain proper humidity.
  • Humidity Control: Proper humidity is crucial. Too dry, and the eggs will desiccate. Too wet, and they can rot.

    • Place a small cup of water in the incubator to act as a humidifier.
    • Alternatively, regularly mist the substrate with water to keep it slightly damp, but not soaked.
  • Temperature Monitoring: Temperature is critical for determining the sex of the turtles in many species.

    • Use a reliable thermometer placed near the eggs to monitor the temperature.

Incubation Temperature and Sex Determination

  • Temperature Range: Aim for a temperature range of 82-86°F (28-30°C). This is a general guideline; research the specific temperature requirements for your turtle species, as some species may require slightly different temperatures.

  • Sex Determination: In many turtle species, the incubation temperature determines the sex of the hatchlings. Higher temperatures often produce females, while lower temperatures often produce males. The exact temperature that produces only males or females varies between species, and some species don't exhibit temperature-dependent sex determination. Research your specific turtle species!

Incubating the Eggs

  • Handling the Eggs: Handle the eggs very carefully. Do not turn the eggs after they are laid. Mark the top of the eggs with a pencil before moving them, so you can ensure they stay in the same orientation throughout incubation.

  • Placement: Place the eggs in the chosen substrate, partially burying them if using the sand/vermiculite/perlite method. If using an egg carton, ensure they are secure and won't roll.

  • Monitoring: Check the eggs regularly for signs of mold or fungus. Remove any bad eggs immediately to prevent the spread of contamination. Maintain the proper humidity and temperature.

  • Patience: Incubation times vary depending on the species and temperature, but it typically takes anywhere from 50 to 120 days.

Hatching

  • Allow Hatching: Once the eggs start to hatch, allow the hatchlings to emerge on their own.

  • Newborn Care: Once hatched, move the hatchlings to a suitable enclosure with appropriate food and water.

Important Considerations:

  • Species-Specific Requirements: The specific temperature and humidity requirements vary greatly depending on the turtle species. Research the needs of your specific species thoroughly.
  • Legality: Owning and breeding certain turtle species may be illegal in your area. Check your local laws and regulations.
  • Ethical Considerations: Ensure you can provide adequate care for the hatchlings before attempting to incubate turtle eggs.
