The average time for a scalloped chicken to be released is about 120 days. 7 months in the wild and 4 months in captivity. A fan chicken is a castrated chicken. Before castration, roosters are very aggressive and active, and tend to consume the feed fed to them very quickly, resulting in high costs of raising chickens and poor meat quality. Castrated chickens will have a drastic change in temperament and can even take the place of a hen in caring for her chicks.
