Will the body temp of a hen be enough to successfully hatch duck eggs?

No, a hen's body temperature is not enough to successfully hatch duck eggs.

Here's why:

* Different incubation temperatures: Duck eggs require a slightly higher incubation temperature than chicken eggs.

* Chicken eggs: 99.5°F (37.5°C)

* Duck eggs: 99.5°F - 100°F (37.5°C - 38°C)

* Humidity: Duck eggs also require a higher humidity level than chicken eggs during incubation.

* Turning: Duck eggs need to be turned more frequently than chicken eggs to ensure proper development.

While a hen might keep duck eggs warm, she won't be able to provide the necessary temperature, humidity, and turning that duck eggs need to hatch successfully.

You'll need an incubator specifically designed for duck eggs to ensure the best chance of hatching.
