I read through about half of the posts, so forgive me if I repeat what others have already said.
To the OP:
For long term solutions you need to build enclosures to secure your animals in at night. You will also want strong hotwire going around your property. You should have lower strands as well as high ones. These steps will be expensive, but less costly then replacing animals and certainly less then if you are caught shooting a wolf illegally.
We live in mountain lion country, and having our animals out in the open all night would be begging for problems. It wouldn't be the cat's fault, but mine for not taking steps to protect them. Heck, I just dangled food right in front of them, of course they will take advantage of it.
I have no issue with people killing known predators, however it should not be the first line of defense. There will always be more predators to fill the gaps you just created, it's far more effective in the long run to think defensively (fencing, etc.).
I'm in Western OR, there are now wolves in Eastern OR and they are making their way west. I suspect that within the next 5-10 years we will have wolves established here. It's going to be very interesting to see how it shifts around the predator balance. I am hoping that the raccoons and coyote take a hit, maybe even some of the younger cougar.
Anyway, good luck to you. Shore up your defenses.
