Weasels are the sly, sneaky predators of the chicken coop. Most people rarely encounter weasels, but many poultry farmers have witnessed the massacre a weasel can leave in its wake. Similar to its cousin the mink, weasels are efficient killers – sometimes killing more than they can eat. Weasels primarily prey on chickens, mice, chipmunks, and rabbits.
Weasels are nocturnal creatures. Not only are they quite elusive, but they move very swiftly in zigzagging patterns, darting from shadow to shadow. There are 3 species of weasels in Wisconsin: the long-tailed, the short-tailed, and the least weasel. They typically have short fur that is light brown above with a cream-colored throat and belly. During the winters, a weasel’s coat changes to white to help better blend into the snow.
