How warm does a swallow egg have to be to hatch?

Swallow eggs typically need to be incubated at a temperature of about 35 to 37 degrees Celsius (95 to 98.6 degrees Fahrenheit) to hatch successfully. This temperature range is crucial for proper embryonic development. The incubation period usually lasts around 12 to 14 days, depending on the species and environmental conditions. Maintaining consistent warmth is essential for the eggs to develop properly and hatch effectively.
