I went out to feed today and found 5 dead and 3 limping around. Anyone have any idea what might have attacked? I read the sticky with no luck. Chickens were whole and appeared unhurt. no blood, and no feathers out of place. I have one silkie that wont even get up to walk, 1 EE roo that is limping, and one bantam thats moving slowly. I live in NC if that helps anyone narrow down the predator list. Thanks for any help or comments.
