I am moving to SW Florida soon and alligators are a potential threat where we will be living. I am wondering how important smell is to a gator? A well placed tarp can keep a gator from seeing the girls, but does smell factor in? We may be living on a canal with a pond and small back yard. i have two little boys and cannot be attracting gators with chickens. Any advice for constructing a secure AND pretty hen fortress would be much appreciated. Thus far the only predator I have had to think about is birds of prey. Soon I will also be worried about bobcats, gators, snakes, skunks, possums, monitor lizards and coons- oh, my!
