At what degrees the egg trays are tilted in artificial incubation?

Solution (By Examveda Team)

The egg trays are tilted in artificial incubation at 180°.
Artificial incubation involves removing eggs from incubating parents and using an incubator to hatch them.
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. It lets the fetus inside the egg grow without the mother needing to be present to provide the warmth.
