It is always exciting for a turtle owner when his turtle lays eggs. It also adds some extra responsibilities to the owner’s daily schedule.

Each box turtle owner has to make sure that his box turtle and eggs are getting proper care. Taking care of box turtle’s eggs include incubation of the eggs and health care of the hatchlings.

If your box turtle is going to lay eggs for the first time, do not get nervous. You have come to the right place. In this article, I will illustrate everything about the box turtle’s breeding and eggs.

Box Turtle Mating Season

We all have heard about hibernation. It is a biological process, a box turtle may experience during severe cold or weather. Most of the time, a box turtle comes out from hibernation in March or early April. Basically, the time depends on your geographical area, and its weather.

Adult male box turtles feel an urge to find a mate right after coming out from hibernation. They may avoid food or their daily schedule but they will take the chance of reproducing.

The main mating seasons for a box turtle are summer and spring. In captivity, you may often find your box turtle engaged in mating in these seasons. Moreover, you can not force a box turtle to mate at a certain time. If you house multiple box turtle, often they will engage in mating.

Ideal Box Turtle To Breed

A scientific study indicates that not every box turtle is ideal for breeding. Again, many box turtle owners do not want their box turtles to breed. But the main question is why every box turtle is not ideal for breeding.

Improper breeding can cause genetic problems. You should not let siblings breed. This type of breeding affects the next generation of the box turtle.

Again, you can not free your box turtle in the wild to mate with another box turtle. There is a high possibility that the wild box turtles carry germs and diseases. By engaging in a mating process with them, your box turtle can get sick.

How To Find A Good Box Turtle Pair For Breeding?

Finding a good pair for breeding is not hard. All you have to do is to find two box turtles of the opposite gender, and the same species or subspecies. Some subspecies of the box turtle are allowed to breed together. For example, you can breed the Eastern box turtle and three toed box turtles together. But cross-breeding is always demotivated because it can result in genetic abnormalities.

Before choosing a good pair, you have to be an expert in finding the box turtle’s gender. In most cases, the male box turtle has red eyes, and they have a concave curve on the bottom of their shell. The concave curve allows them to mount the female box turtle during sex.

On the other hand, the female box turtles do not have red eyes, and their bottom shell is flat. If you find difficulty in determining the gender of the box turtle, you can take it to the vet.

Moreover, you have to make sure that the pair is healthy and does not have any diseases.

Mating can be a stressful process for the box turtles. So, make sure that both the box turtles are strong enough to go through the process.

Set Up For The Breeding Process For Box Turtles

As a responsible turtle owner, you should make sure that your box turtle is getting everything it needs inside the enclosure. It is even more necessary if you are planning to engage them in mating.

You have to provide fresh water in the water source. The water should be deep enough for the box turtles to sink in. Set the heating lamp at the edge of the enclosure so that the box turtles can move from the warm side to the cool side if they want.

Put brush, logs, and hiding places for the turtles’ privacy. Provide soft material or soft bedding so that the box turtles can burrow into it. Make sure that the walls of the enclosure are covered with paper or anything else.

You have to build a second enclosure for the female box turtle. She will need it after breeding. Moreover, you also have to prepare a place where the female box turtle will lay eggs.

How To Take Care Of Box Turtle Breeding Pair?

  • Do not let the related box turtles breed together. It means no brother-sister, mother-son, or daughter-father should make the pairings. It causes genetic abnormalities in the next generation.
  • Take care of their health. Make sure the pair is getting enough Vitamins, calcium, and minerals.
  • In any case, if the female box turtle falls sick, do not let it breed. A sick female box turtle lays thin-shelled eggs or undeveloped eggs. Moreover, eggs can cause internal damages to a sick female box turtle. The box turtle can die in severe conditions.

How Would You Know That Your Box Turtle Is Going To Lay Eggs?

When a female box turtle is ready to lay eggs, you may notice some changes in its behavior.

  • Your box turtle will start digging holes into the substrate. It will dig holes in various places to find the perfect spot for laying eggs.
  • She will walk in a different style than usual.
  • She will be restless and may show some weird behavior like jumping.
  • The female box turtle will lose her appetite.
  • Her digging pattern will be different. The most important thing to notice is that the hole will be deeper.
  • The hole will be as deep as the length of her body. After finishing digging, she will get inside the hole, lay eggs, cover the eggs with mud, dirt, and leaves, and never come back for the eggs. So, if you want to move the female box turtle to another enclosure for laying eggs, you have to move just after noticing her unusual behavior.

For this reason, many box turtle owners or turtle keepers provide nesting boxes to the mother turtle. If the soil of the enclosure is soft and deep enough, then you do not need to provide a nesting box.

  • We know that a female box turtle does not lay eggs until she finds a suitable place for laying eggs. She may keep the eggs inside her, which is risky. A nesting box assures a suitable place for laying eggs to the box turtle.

  • You can mark the top of the eggs with something so that you can make sure the position of the eggs.

The Temperature Of The Incubation

The ideal temperature for incubation is 85 degrees to 90 degrees Fahrenheit. The temperature can vary from subspecies to subspecies. You can also apply a lower temperature but the process will go for a long time.

The Humidity Of The Incubation

Hardshell eggs require 70% humidity, and soft shell eggs need 90% humidity for incubation. American box turtles lay soft shell eggs. So, they need 90% humidity.

Duration Of Incubation

Most subspecies or species of box turtles need 8 to 11 weeks to hatch. In some cases, they may need one or two extra weeks.

You have to moist the substrate regularly. If you provide proper temperature and humidity, the eggs will hatch properly.

You have to be patient during this process. Do not toss any eggs just because you think it is infertile.
