This follows a nationwide operation in which about 2000 chicks were rescued from the dam last month.
The conditions of the dam are deteriorating because of climate change and a lack of water. It has also led to a decline in blue-green algae, which the birds feed on. This led to the adult population leaving the dam.
Kamfers Dam is one of the biggest breeding colonies for lesser flamingos in Africa.
Meanwhile, Birdlife SA is trying to bring water to the dam for the chicks, but it and similar organisations are discussing what to do.
