Overview
The Turkey is a landfowl, and its eggs hatch in about 28 days, with a normal window of days 27-29. Incubation difficulty is rated Beginner. Below you'll find the temperature, humidity, turning, candling and hatching steps for this species.

Large meat bird with chicken-like incubation needs but a longer 28-day term.
The Turkey is a landfowl, and its eggs hatch in about 28 days, with a normal window of days 27-29. Incubation difficulty is rated Beginner. Below you'll find the temperature, humidity, turning, candling and hatching steps for this species.
In a forced-air (fan) incubator, hold the temperature steady at 37.4-37.6 °C and target 50-55% relative humidity in the first stage. Verify the readout with a reliable digital thermometer and hygrometer.
Turn the eggs an odd number of times per day, 5 times, so the embryo doesn't stick to the shell. Recommended candling days: 8, 14, 25. In a dark room, hold the egg to a strong light; a vein network and movement show fertility, and clear eggs should be removed.
On day 25, stop turning (lockdown), raise humidity to 65-70% and keep the incubator closed as much as possible. Hatching is expected on days 27-29; once chicks start pipping the shell, be patient, as hatching can take hours.
Leave the chicks in the incubator until their down dries and they perk up, then move them to a brooder kept at 35 °C for the first week, lowering the heat by about 3 °C each week. Provide clean water and quality starter feed at all times.
Turkey eggs usually hatch in 28 days, with a normal window of days 27-29.
In a forced-air incubator, 37.4-37.6 °C and 50-55% humidity are recommended; during lockdown humidity is raised to 65-70%.
Recommended candling days: 8, 14, 25. Remove any clear or non-developing eggs at these checks.
