I'm sorry, but this question CANNOT be answered, because you did not specify the species of gecko.
Geckos come from habitats as diverse as desert scrubland, tropical rainforest, and cool montane rainforest. Popular pet species range from animals that will die if kept over 80F, to those that will die if kept UNDER 80F.
Obviously, the temperature of egg incubation varies accordingly.
All reptile eggs need incubation to hatch.
Ideal temperature for incubation is 100.5 F and 60% humidity
The average incubation of a python egg is about 50-55 days. The temperature must be kept at about 89 degrees Fahrenheit.
Egg incubation
Unlike chickens, turkeys take 28 days to hatch. The ideal temperature for incubation of a turkey egg is 99F and a humidity of 60%+. Turkey eggs need to be turned as much as 5 times every 24 hours. Large drops in temperature can slow or even stop embryo development. Keep the eggs away from drafts and rapid temperature fluctuations.
Depending on the specie, will determine the incubation period. Species in smaller size will usually have a smaller egg, which will have a shorter incubation period than a larger specie. Typically eggs will take 40-120 days in most common gecko species.
It depends on what type of gecko.
The optimal temperature for sea turtle egg incubation is 23 to 33 degrees Celsius.
Hatching of eggs depends upon temperature , 21 to 60 days .
incubation
if you keep the eggs at around 50 degrees the egg will last about 5 days before you need to start incubation but sooner is always better
Yes. It can.
