lost 3 ducks and 4 chickens one day. thats when i was away at my dads. not that im back from my dads ive lost 3-5 chickens and they only dissapear when im not outside. so whatever it is,is watching me and knows that when im inside my birds are vunerable and whatever it is grabs one and takes off. what could it be? what would do so often. lost 1 bird one day, two days later lost another,then the next day lost another one. and that was yesterday.
