The typical gestation time for a pygmy goat is 21 weeks. Though kids develop at different rates, there are some basic milestones in pygmy goat fetal development.
At four weeks gestation, the fetus is less than 1/2-inch in size. On a sonogram, the kid's facial features and small stumps where the legs will form are visible.
Only fifteen short days later, the kid is about 1-inch longer and weighs approximately 1/4-ounce. The goat has eyelids by this point. Its legs and developing neck have grown longer.
A great deal of growth occurs during the next stage, and by this point it weighs 4 ounces and is 2 1/2 inches long. The kid's first hairs have sprouted around its eyes and mouth.
One month later, the fetus is 18 ounces and over 3 inches long. Formative hairs are now growing all over its body.
At four months, the kid weights 2 lbs. and is 6 inches long. Its fur coat has finished growing, and its legs are fully developed.
Just before birth, the baby goat weighs up to 4 lbs. Its organ systems are mature and its teeth have erupted from gums.
