THIS Florida prison has a furry little secret - a zoo full of alpacas, birds, alligators, a lemur and even a sloth. The farm at Stock Island Detention Centre, in Key West was founded by accident in 1994 when the prison fenced off an area underneath to protect a gaggle of ducks that kept getting injured while crossing the road between the jail and a golf course. Now the prison is home to over 150 animals, ranging from the original ducks and farm animals to alligators and a ten foot python. Jeanne Selander, who manages the farm, takes four volunteers from the prison to help care for the animals and maintain the farm.
