Several roosters have found their way to Hen Harbor. They keep careful watch over the hens and are an important part of the Hen Harbor community.

Unwanted roosters are an unfortunate artifact of the backyard chicken trend. People who purchase chicks from hatcheries expecting them to grow into egg-laying hens frequently end up with an unexpected rooster in the batch. Most of these roosters end up being killed owing to zoning ordinances, and because most animal sanctuaries are already filled to capacity with discarded roosters.
