How do you hatch a barnswallow egg?

To hatch a barn swallow egg, you'll need to mimic the natural conditions of a nest. Ensure the eggs are kept in a warm and stable environment, ideally around 98.6°F (37°C), as barn swallow eggs require consistent warmth to develop. It's important to maintain humidity levels and avoid disturbing the eggs too much. In the wild, the parent swallows will incubate the eggs, so if you're attempting to do this artificially, be prepared to provide constant care and attention.
