an egg incubator
Common cuckoos do not build their own nests or incubate their eggs. Instead, they lay their eggs in the nests of other bird species and rely on the host bird to incubate the eggs and raise the cuckoo chick.
NO salmon dont incubate their eggs, fish dont incubate their eggs at all, they lay them and the male fish swims by the fish and releases the sperm near the eggs and they become fertilized outside of the female fish.
Both Female and Male Eagles incubate the eggs. They actually take turns.

Hello, you should incubate the eggs at around 84 degrees F :)
When they have hatched otherwise they will die!!!

Incubating the eggs was necessary for their survival.
You didn't give a specific type of heron in your question, but Great Blue Herons usually incubate their eggs for 26-29 days.
Don't do that, the temperature is too high and not suitable for eggs incubation.
you will more than likely still incubate the egg
