I have to look at bears as the obvious example. We have a local sow bear, though I have never seen it. My neighbor reported she was hanging out in their yard though, tearing up their saplings. I'm fully aware that short of electric fencing or steel walls, a bear can pretty much get into whatever it wants. So sorry chickens, if Ms. Bear decides to have chicken for dinner, I'm hiding inside the house
(though from all reports she's lazy and goes for easy meals like bird feeders and cat food dishes).
With other things, I'd either send my hubby out or at least one of our dogs. Had a small coyote eyeing the run back in December and I heard the chickens alarm call, so I ran out with an axe handle, but it was already hightailing it out of there. In hindsight I should've brought my Anatolian with me too.

So sorry. 
My gander is the best though. He is so sweet and he actually attacked a dog who was digging into our chicken coop and ran it off. He was only 2 months old when that happened. I ran out there when I heard a dog yelp. He bit it hard. I'm glad too because the neighbors are so irresponsible with that dog. It killed our first set of beloved birds, and it tried to get the new ones too. He comes in the house sometimes and he loves to cuddle. A friend gave me a single goose egg and I incubated it and he hatched. He is a really good guard goose. He just seems smarter to me too. I do love my chickens, but I don't think I would ever risk my life for them. Birds are replacable, people aren't. IMHO
