• Pro tip: Always measure egg dimensions before loading to ensure adequate spacing for proper airflow and development.

Maintaining accurate humidity is crucial for embryo development and successful hatching. The ideal humidity settings vary depending on the stage of the incubation cycle:

• During incubation (Days 1–18 for chickens): Maintain a steady humidity level of around 40–50%. This range helps prevent excessive moisture loss from the egg while allowing proper air cell formation.
• During hatching (Days 19–21 for chickens): Increase humidity to 65–70% to keep the egg membranes moist, preventing the chick from sticking and aiding in smooth pipping and hatching.

To achieve and maintain these levels, your incubator should be equipped with a reliable digital hygrometer and a precision humidity controller. Regular calibration of these instruments ensures accuracy. Additionally, water trays should be refilled as needed (using distilled water to prevent mineral buildup), and ventilation adjusted according to ambient room conditions.

Fluctuations outside these ranges can lead to dehydration, malpositioned embryos, or failed hatch attempts—so consistent monitoring is essential.

No, the 72-egg mini incubator is designed for **indoor use only** and should never be placed in open outdoor environments. Exposure to external elements can severely compromise its performance and longevity.

Outdoor conditions such as temperature swings, humidity fluctuations, direct sunlight, wind, dust, and rain can interfere with the incubator’s ability to maintain a stable internal climate. Even in sheltered areas like patios or garages, uncontrolled drafts and ambient temperature changes can cause dangerous deviations in heat and moisture levels—jeopardizing embryo survival.

For optimal results, place the incubator in a clean, climate-controlled indoor space that is:
