Why do parakeets kill their own baby's?

Parakeets may kill their own chicks for several reasons, including stress, overcrowding, or inadequate nesting conditions. Sometimes, a parent may perceive a chick as weak or unhealthy and remove it from the nest to ensure the survival of stronger offspring. Additionally, hormonal imbalances or lack of experience in first-time parents can lead to such behavior. It's essential for owners to provide a calm, secure environment to reduce stress and promote healthy parenting.
