Yes, all birds can lay unfertilized eggs. This is part of their reproductive cycle. Hens, for example, lay unfertilized eggs regularly. In the wild, some birds might do so at the start of their breeding season. Unfertilized eggs will not develop into chicks since they lack the necessary sperm. This is a natural process for many bird species.
