Male and female blue duikers will mate for life. After a 7.5 month gestation period, a single offspring is born (twins occurring very rarely). The mother will hide the baby away for 2 -3 months, visiting it to nurse several times a day. Baby blue duikers can stand 20 minutes after birth. After the baby is weaned, it will join its parents in their territory. Females reach maturity at 9 – 12 months, and males 12 – 18 months.

The average blue duiker lifespan is 10 – 12 years. Pairs have a territory of 6 – 10 acres, and will scent mark the boundaries of their territory and chase off any intruders.
