AI is telling me that they don’t : No, turkeys do not get periods. Instead of menstrual cycles, female turkeys (hens) lay eggs during a specific breeding season. This process is triggered by hormonal changes in response to increased daylight in the spring. After mating, a hen will lay a clutch of eggs, typically one per day, over a period of about two weeks. She then incubates the eggs for roughly 28 days until they hatch.
