Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg. Multiple and various factors are vital to the incubation of various species of animal. In many species of reptile for example, no fixed temperature is necessary, but the actual temperature determines the sex ratio of the offspring.
A modern egg incubator. An incubator is a device simulating avian incubation by keeping eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them. The common names of the incubator in other terms include breeding / hatching machines or hatchers, setters, and egg breeding / equipment. [1]
Pattern IA has a single transition zone, where eggs predominantly hatch males if incubated below this temperature zone, and predominantly hatch females if incubated above it. Pattern IA occurs in most turtles , with the transition between male-producing temperatures and female-producing temperatures occurring over a range of temperatures as ...
The eggs are laid near the water so the hatchlings can return to the sea. [66] The loggerhead's sex is dictated by the temperature of the underground nest. Incubation temperatures generally range from 26–32 °C (79–90 °F). Sea turtle eggs kept at a constant incubating temperature of 32 °C become females. Eggs incubating at 28 °C become ...

The eggs need to be maintained at a temperature of 31 to 32 °C (88 to 90 °F) for the production of male offspring. The incubation period is about 115 days and the female caiman remains near the nest for at least the earlier part of this time, providing protection against predators. During incubation, roots may grow through the nest, and soil ...
Mixing eggs straight from the fridge into room-temperature butter causes a temperature disparity that can shock the fat, leading it to seize and curdle. This will ultimately not prove beneficial ...
It carries the ootheca (egg capsule), which holds about 20-35 eggs, until they are ready to hatch, or may drop it earlier under stress conditions. [12] Adults live for up to 2 years, females slightly longer than males. [12] Growth and reproduction rates are sensitive to environmental conditions, optimally 25–30°C and above 60% relative ...
