Even though it can be an uncomfortable subject sometimes, you may be wondering if, like humans, ducks have periods.
Unlike some animals, ducks do not have periods. They ovulate, but they do not have menstrual cycles, and without a menstrual cycle, ducks cannot have periods.
Most ducks are seasonal layers, and seasonal laying birds have 3 phases of reproductive system development. These phases are the prenuptial acceleration phase, the culmination phase, and the refractory period.
Ovulation in ducks is triggered by an increase in two hormones. These hormones are follicle-stimulating hormone and luteinizing hormone.
