My 2 girls that I had exact breeding dates for both had twin boys 2 days early has any one noticed weather typically the goats if having girl(s) have them earlier or later then those that are having boys? I have herd some people say that one gender usually comes earlier then the other just wondering if anyone haas noticed that

Yes, I have noticed boys deliver early and girls gestate a day or two longer. So, at least when your doe is over due you can feel a little more confident about getting a doe.

I would say since boys tend to be larger they may not need an extra day or two to cook.

Apparently my observations were not based on science at all. Here's the result of a study about goat gestation:
Data, collected at a centre in north-eat Mexico on 1468 pregnancies and 2356 newborn goat kids, born between 1991 and 1996, of 6 genetic groups (Alpine, Granada, Nubian, Saanen, Toggenburg and crossbred)under intensive management were used to determine some genetic and non-genetic factors affecting gestation length, and to assess the relationship between gestation length and survival of kids to 25 days of age. The study revealed significant (P<0.01) effect of breed of dam, litter weight, breeding season and parity on gestation length. Number of kids born and sex of kids were not a significant source of variation affecting this trait. Granada goats had the shortest gestation (149.0±0.31 days), whereas Toggenburg (151.7±0.28 days) and Alpine (151.4±0.46 days) had the longest. Litter weight and gestation period were related curvilinearly in summer and linearly in autumn. Gestation of goats bred in summer was 1 day longer (P<0.01) than those mated in the autumn. There was a progressive reduction of gestation length as parity increased (151.3±0.24, 150.6±0.17 and 149.9±0.39 days for 1, 2-6 and >7 kiddings respectively). The mean survival rate of kids gestated <148 days and 148-152 days were 78±2 and 87±1, respectively, and these were significantly lower (P<0.05) than the survival rate of kids gestated 152-156 days and >156 days (94±1 and 95±2). Prolonged gestation (152-160 days) in goats was beneficial because it resulted in heavier litters at birth and higher viability of neonatal kids.
