Oh, her and the rooster have wrecked mice. We're on the edge of town, right next to farmland, so we get mice coming through regularly. It's pretty common to find little shreds of fur and bone when they're particularly predatory.
Hell, the cats we had over the years weren't as vicious as these birds.
Yeah, every time I see this meme, every person who's ever owned chickens immediately chimes in with some version of "Believe me, they know." Because the little buggers really do.
Destroyed? As in slaughtered for no reason, none. If we're talking about how many died to feed my family and neighbors and friends; several hundred. And I continue to do so to this day. If you don't like that, I don't care.
