The difference between goose hatching and egg hatching
The incubation period varies depending on the type of egg. For example, chicken eggs typically require 21 days, while some other species may take up to 30 days. During the final stages of hatching, it's crucial to manage the environment carefully. As the embryos develop, their metabolic activity increases significantly after day 18. Since the eggs are large and rich in fat, they generate more heat, which needs to be regulated.
To prevent overheating, it's recommended to ventilate the eggs starting from day 18. This should be done twice a day—once in the afternoon for about 30 minutes each time. The goal is to allow the egg temperature to drop slightly to around 36.6°C. After this ventilation process, misting the eggs with warm water at 30°C can help cool them down and increase the humidity around the eggs, creating a better hatching environment.
For goose eggs, the incubation temperature is generally 1°C to 2°C lower than that for chicken eggs. The ideal temperature for goose eggs is 37.8°C during the first six days, then gradually decreases to 37.5°C between days 7–12, 37.2°C from day 13–18, 36.9°C from day 19–28, and finally 36.6°C from day 29 to 31. Humidity levels also vary throughout the process: 70% in the early stage, 55% in the middle, and 60% in the later phase.
Modern hatchers often use automated systems to maintain optimal conditions. It’s important to set the temperature and humidity correctly at the start and monitor the machine to avoid power failures. Around day 18, it's common to mark or line up the eggs for easier monitoring.
If using traditional methods, such as a fire bowl, place a 5 cm layer of fine sand on the bottom, cover it with soft grass or a cloth, and position the eggs on top. A thermometer should be placed on the surface of the eggs to monitor the temperature. Eggs should be turned every 2–3 hours, and additional insulation like an egg or a blanket can be added based on the ambient temperature.
When using a water bag method, simply place the eggs directly on the bag. The water bag should be about 10 cm thick, covered with a simple plastic sheet filled with hot and cold water. Roll the edges of the plastic and surround the bag with wood or another frame to keep it stable. Hot water can be added 1–2 times during incubation to adjust the temperature as needed. This method helps maintain consistent warmth and moisture, supporting healthy embryonic development.
