Minks/Weasels

Weasels and minks are infamous for murdering chickens for amusement. Frequently, they'll murder some chickens, leave them to rot in the coop, and then go kill another. The skull and internal organs of the deceased chicken are occasionally consumed by these predators. These horrifying creatures wrap themselves around hens and bite them on the neck as a form of entertainment. They will eliminate a whole flock in a single night, or if they are unsuccessful, they will return repeatedly until all the chickens are dead.

Another serious threat to chickens is the weasel, another tiny, burrowing predator. Weasels and minks have been known to kill mature chickens despite their size. Weasels are nimble, astute, and voracious predators. A single weasel may destroy a small flock in a single night and to make matters worse, they may just bite the chickens' necks to drain their blood, leaving the rest to waste. They frequently hunt wastefully, much as raccoons do. A weasel behind the attack if you discover a dead chicken with lacerations or missing guts.
