Weaning size is largely controlled by how much milk the mother produces, along with how long she allows each kid to nurse.
The presence of a buck causes does to come into estrus (heat), which lasts about 24–36 hours. The gestation period for does varies from 149 to 155 days.
Boer does are normally very good mothers, requiring only minimal attention from the owner; however, this is not always true when a doe delivers her very first kid.
First time does should be supervised, as the mothering instinct may not manifest itself the first time she delivers. After the first time, Boer does normally make excellent mothers.
