Last Tuesday I went out side to check on my animals. I was walking towards my chicken pin and seen a bunch of feathers and my 2 white silky hens laying on the ground dead. I had 10 chickens all together. 3 silkys and 7 easter egg chickens. I lost all but 2 of my easter egg chickens. Then last night something killed one of my ducks. There is no blood on them. They just look I guess like they were killed for fun by a animal. Which makes no sence to me. Does anybody have any idea what it could be? Or how to stop it? Please help. I can't stand to lose anymore of my babies.
