First Attack in Six Years - What Kind of Predator?

My first thought would be a coon. Possibly a possum, but usually they start at the other end in my experience.

If there are any holes larger than about two inches in your night coop you need to get them covered.

Seeing as how you are up north and particularly if you are anywhere close to water if there are any holes larger than an inch you need to rectify the situation. Weasels, minks, martens, and some others that I am not very familiar with down here in Florida can squeeze through some mighty small holes.

We had a weasel get into our coop and kill four of our hens.  There was no blood. 

I'm sorry this happened to you.

We lost our entire flock last night, just devastating! 10 birds 2 partially eaten and torn apart the others just killed for fun. makes me sick. i'm sorry for your loss.

I'm out for blood too, i'm gonna trap in tonight hopefully and take my 20 gauge to it. then enjoy my revenge, sorry i know it sounds crazy but i'm just so mad! i will take a pic of my first animal kill if i get it, i think it was a coon from what it looks like. i don't think anything else would've gotten back out as it came from the top of the cage.

Sounds like a raccoon. We've had raccoons get in any way they can, including digging and slipping inside. They even pull the chickens through the bars. (One of our most favorite little roosters was pulled through the bars of a cage, as well as another chicken.) Coons are really smart. We've trapped several, but in at least one case, the raccoon tried digging all the way around before he went in the opening. Crazy.

 

So sorry about what happened to you. We always keep our wire fixed up (though when we notice it, it sometimes is after an attack.)

 

I hate coons.

I have not had any coons get my birds but have had possum, fox, coyotes, dog, bobcat and a skunk after my birds. I now have electric up and anything that touches the fence gets zapped. I have not lost a bird since electrifying. I have heard critters make contact with the wire and they don't come back to check it out again. Most of the predators have been diggers. I believe in sss.

Lost an entire flock of 15 pullets in the last 3 nights to something evil too. Not sure what, though I suspect weasels. Ate everything but the legs off some of them, just killed others because they could. I cannot figure out how they got in and out last night. I'd found a spot where a clean out door was ajar a couple inches and boarded it up tight leaving no openings at all. Very angry at this point. My last flock that I had for 3 years never had anything like this happen. I lost them during the day to dogs, but never at night like this. Evil, evil creatures...
