A friend of mine and her next door neighbor lost 30 chickens in one night. I am not sure how secure their coops are, but I do know they have not had previous trouble with losses. Most of the chickens were chicks that I think were about 2 months old. The birds simply disappeared. There is no sign of a break in. No feathers, no blood...nothing. They have searched and searched acres around their homes. They are both sad and frustrated of course. Can anyone think of something that would/could do this?
