Incorrect that Nigerian Dwarves have shorter gestation periods because they have more, but smaller kids. Even Nigerian Dwarves who kid only one or two kids tend to kid closer to day 145. Same with pygmies.
Okay, you sure could be right! I have ND's but they've usually given me trips & quads and kid on Day 140- something. : ) Course, I did have a doe kid twins one time on Day 141!! Yep, I think you've got a point.
