I had a very disappointing morning today as I woke up to find that something has killed 28 of my chickens. Whatever animal it was, it didn't eat hardly any of the birds, it just killed and left them laying. I am thinking that it is probably a coon or someone's dog. Whatever it is has messed with the wrong guy.

Oh man... sorry to hear that.

After reading that first sentence, dog popped in my mind before I read it in your post. If it didn't eat anything, it probably already had a meal. Good luck getting after it whatever it was.

It was most likely a possum.
They do that.
Was some of the chickens heads missing?
They just eat a little, and go on to another one.
Just my 2 cents.

Most of them didn't have a mark on them. A few were ripped open and just a mess.

Weasels will do the same thing. Just a thought.

Sorry , Good luck in yer quest.

i am very sorry to hear about it thats really a shocking one to hear up

Minks will do that to Chickens also....set You out a trail camera and wait up a few nights to kill the Culprit,maybe even put out a motion light so You can see what's out there to shoot?

These guys pretty much have it covered. Weasel, mink or possum would be my guess. You could set a few traps and see what you catch.
