International Journal of Advanced MultidisciplinaryBroodless egg hatching is often the choice of farmers when the mother does not incubate her eggs. However, to ensure hatching success, careful monitoring of temperature, humidity, and heat distribution in the incubator is essential. This thesis aims to develop an Internet of Things (IoT)-based automatic egg hatching control and monitoring system to ...

Effects of hatching time and hatching system on broiler chick development
Key words: hatching time, hatching system, chick physiology, broiler growth, chick quality. Chicks hatch over a time window of 24-36 hours and are only removed from the hatcher when the majority of the chicks have hatched. Especially for the early hatching chicks this leads to delays in the first feed and water access and consequently negative effects ...
