Below are some general guidelines and simple techniques that can lead to successful incubation. It really depends on the individual tortoise. Chalking is the first sign of a fertile egg. Although blood vessels can be seen, Egg 3 still looks different. I own a 3 year old Hermann's Tortoise called Terry. called an egg-tooth. carton with the top removed, and placing it in a spare vivarium (if you have one). This is what it looked like when candled and then under regular lighting. If a female determines that she doesn’t have access to a suitable nesting site, she will instinctively hold her eggs in. â¢ Check the eggs regularly to make sure that the substrate remains damp. Position the goose-neck lamp next to the bucket and move the light close to the sand surface. Mold and odor are not good signs. DAY 25 – Egg 3 finally chalked, 9 days behind the first egg. Eight weeks ago this pair was responsible for two more eggs going into the incubator. Posted in Redfoot tortoise egg development, Redfoot tortoise eggs, Redfoot tortoise embryo, Tagged Chelonoidis carbonaria, Incubating Redfoot eggs, Redfoot tortoise, Redfoot tortoise twin embryos, Tortoise. Place a thermometer by the eggs. Within 2 days, the eggs of many species will "chalk over", that is the shell will become a more opaque, chalky, white color. If you’re planning on breeding tortoises semi professionally then your best bet is to opt for a commercially available incubator, the kind of thing typically designed for chicks. A little over a month ago, two more eggs were added to the incubator. When you think about it, creating eggs takes a lot of energy and nutrition that the mother tortoise could otherwise benefit from herself. A couple of days later, I noticed an odor when opening the incubator. Zoe spent quite a bit of time earlier in the week finding her nest site and she chose another rain drizzled day for laying. Yesterday, Day 63, I was able to see definitely one embryo developing at the bottom of the egg, just off center. Just as more mature tortoises are able to metabolize their food more effectively, and move more quickly when the ambient temperature around them is optimal; developing hatchlings are also able to grow more quickly if they are incubated within the correct temperature range. During incubation turtle and tortoise eggs can be candled to check on their development. Chalking is the very first sign that a fertile egg is developing. The most important thing to remember about incubation is that you must be able to maintain a consistent temperature for the duration of the process. DAY 16 – Egg 1 chalked. Along with their strange behavior you can get a rough idea of whether a tortoise is in egg laying mode by the time of year. I certainly wouldn’t want her retaining an egg, which may cause her harm days or weeks later. Some eggs of water turtles and semi-terrestrial Last week I noticed a difference in development of Zoe’s January clutch of two. This is just a theory however!eval(ez_write_tag([[300,250],'tortoiseexpert_com-leader-1','ezslot_1',111,'0','0'])); If your tortoise does lay eggs you’ll want to be able to determine whether or not they contain fledgling tortoises as soon as possible, so that you can provide the right conditions for them to grow and develop, and with any luck, hatch. This egg should hatch mid to late June. There was nothing recognizable inside. It becomes more opaque and chalky white in color. When the female has finished laying, open the nest and carefully remove the eggs. eval(ez_write_tag([[250,250],'tortoiseexpert_com-banner-1','ezslot_3',109,'0','0'])); For a nesting hole to retain its shape the soil must be suitably claggy, therefore very sandy soils aren’t preferred.
I’m not sure whether it’s a pheromone or some other mechanism, but when a female is in the presence of a male, yet without actually mating with him, she is more likely to produce eggs than if kept exclusively with other females, or indeed on her own.
It’s been two to three weeks since the photos were taken of the Redfoot egg that I suspected to be twins. After carefully removing the eggs from the nest, lightly mark a cross or number on the top of each one with a pencil. Development shown in photos below.

Time will tell.
Incubation and hatching of tortoise eggs in the UK can be an extremely critical time for the tortoise breeder. Below is a comparison at Day 45, Day 48 and Day 50. Adjust the temperature of the sand by moving the lamp closer or further away. An air sac is starting to form, and if it gets moved, there is a possibility it could rupture and cause the egg to go bad. If the nest has been filled in, dig out the soil using a spoon, paintbrush or other small This incubation journey will take between 120 and 150 days. Posted in Redfoot tortoise egg development, Redfoot tortoise eggs, Tortoise egg incubation, Tagged Incubating Redfoot eggs, Redfoot tortoise egg chalking. It could be a couple of days before it is free from the egg. Chalking is the very first sign that a fertile egg is developing. It was chilly that day, especially with the rain, and I decided to do things a little differently.
Development shown in photos below. Placing the eggs directly under, and closer to the heat lamp than usual should expose them to the higher temperature they require, but of course you’ll need to check the ambient air temperature between the lamp and the eggs when you do so, Carefully burying the eggs in a bucket of sand so that they are just visible below the surface.
New-laid turtle and tortoise eggs tend to have a bluish-white hue. Slightly sloped areas are preferred because any moisture is able to drain away, and likewise areas in direct sunlight ensure the eggs are (in theory at least) suitably incubated.
Most sources seem to agree that tortoise’s, and possibly other reptiles differ from mammals entirely in this regard in that they don’t experience the menopause.
This hatching season should end with a total of six beautiful, healthy hatchlings. Essentially females have the ability to store sperm in their bodies for months and even years at a time!
The time taken for eggs to hatch depends upon both the type of turtle and the incubation temperature. Use a thermometer, placed by the eggs, to monitor the temperature. I still see a second circular shadow that appears to have grown, but it’s unclear to me whether it’s just blood vessels or an embryo that perhaps has stopped developing. â¢ Keep the temperature at about 80Â° F (27Â° C).
I expect this clutch of three to hatch in the next 3 to 6 weeks.
Hold the egg over a pencil light or other narrow beam of light. There are many considerations that the breeder needs to take into account when a reproductively active female is ready to lay her eggs if there is to be a successful outcome. The eggs may not all hatch at once, so be sure to leave any unhatched eggs to incubate longer, just in case. Once they reach maturity you might find they lay eggs, perhaps on just one single occasion, every year, or somewhere in between. DAY 6-9 – Thickening of the yolk at the bottom of two eggs. eval(ez_write_tag([[250,250],'tortoiseexpert_com-large-mobile-banner-2','ezslot_10',112,'0','0'])); The other trick to see what’s going on inside an egg is a technique known as ‘candling’, which as the name suggests involves shining a bright light through the egg. DAY 20 – Egg 2 chalked while Egg 3 looks empty. By the way, here’s her nesting sight during and after. Many hobbyists enjoy incubating their turtle's eggs artificially.

It definitely looks different than the other two. This day, however, making sure I was behind her and out of sight, I quietly retrieved the eggs from the nest right as she laid them.

Besides any discomfort and agitation that might be distracting them, the main reason your tortoise will behave this way is because they’re busy looking for a nesting site. The dirt may be packed down tightly, and caution is needed to avoid breaking the eggs. It may take longer for me to find the eggs in the nest after she’s finished and I may break one while digging, but she’ll be healthier for it. It is important to remember that you should only move eggs immediately after they have been laid (usually within two days); as soon as chalking becomes evident it’s a sign that the developing tortoise has latched onto one side of the egg shell where it will continue to develop. Mold growing on the egg at the vermiculite level. I checked on all the eggs and decided to candle the newer ones. The first one was surprisingly sparkly and the second was completely covered with extra calcification. This can then be positioned outside of an enclosure (but away from any potential danger) with a desk lamp (fitted with a heat bulb) angled downwards and facing the eggs.

I learned that it’s best to just wait; let the tortoise begin and finish the process as naturally as possible and without any human interruptions.
