Feral Chicken

Feral chickens are a common sight on all three major islands in the USVI. They can be seen in many different habitats including urban areas, agricultural areas, natural forest, grasslands and shrublands.
Scientific name
Gallus gallus domesticus
Wild chicken
Gallus gallus domesticus are believed to have originated in the Himalayan region, Southeast Asia and Indonesia (Pyle & Pyle 2009).
Your typical chicken, medium sized birds with a wide range of plumage color. Males are slightly larger than females.
Chickens have been widely distributed around the globe and bred as a food source for humans (Pyle & Pyle, 2009). Once in these new locations, like the USVI, chickens have since established wild populations that can cause negative ecological impacts.

Feral chickens live approximately 5-10 years and can breed all year round. Chickens have a high reproductive rate, with females typically having 3- 4 egg clutches per year, and each clutch containing around 8-15 eggs.
