Use this form to calculate your does' due dates!

To calculate her due date, type in her breeding date, put "150" in the # of days box, and press calculate.  I also use this to calculate "heat due" dates, so I know when to watch her especially well for signs of coming back in heat. Use her average cycle length, like 21 days.

Keep in mind that some does, especially early in the season, will come back in heat a week after breeding, which is when they will actually ovulate.  If not rebred at that time, it will be another three weeks (normal cycle) before they come back in heat.

While the Breeding Record generator below is specific to goats, this calculator can be used for any species. Just type in the appropriate number of days of gestation.
