One hatching tank, one aluminum tray, and insulation quilts are used for hatching. Place 30 to 40 pieces of chicken eggs into a small mesh bag and place them in aluminum trays. The outside of the water tank is covered with cotton wool and the like, and the inside is put into warm water of 50-70°C, and the amount of water is not in contact with the bottom of the aluminum plate to be placed. Place the aluminum plate on the tank and cover it with a quilt. At the beginning of incubation, the temperature in the cylinder can be slightly higher. At the same time, there is a large temperature difference between the upper egg and the middle egg in the tray. Turn the egg several times to make the egg temperature basically consistent, then turn the egg once every 4-6 hours. The water in the tank is usually changed 1 or 2 times a day, and only a part of water is changed at a time. A thermometer can be placed in the aluminum pan during incubation to allow for temperature changes.

Beta carotene is the molecule that gives carrots their orange colour. It is part of a family of chemicals called the carotenoids, which are found in many fruit and vegetables, as well as some animal products such as egg yolks. Biologically, beta carotene is most important as the precursor of vitamin A. It also has anti-oxidant properties and may help in preventing cancer and other diseases.
Beta Carotene is also known as a provitamin because it can be converted in our body into vitamin A after oxidative cleavage by beta carotene 15, 150-dioxygenase. In plants, beta carotene, acts as an anti-oxidant and neutralizes singlet oxygen radicals formed during photosynthesis.
