Baby reindeer are not controversial in and of themselves. However, there is an ongoing debate among scientists and conservationists about the ethics of raising reindeer in captivity. Some argue that it is important to preserve the natural environment and allow reindeer to live in their natural habitats, while others claim that captive breeding programs are necessary to ensure the survival of the species. Additionally, there is a concern that raising baby reindeer in captivity may lead to behavioral and psychological issues for the animals.
