I'm so sorry for your loss. I know how terrible those varmits can be. And I love love animals. But I can't stand them killing my chickens all the time.
We have some friends that set traps and kill the wild critters for us, I could never do it myself.
I think in two months alone he caught and killed 4 racoons, 3 skunks, and 6 possums.
I've been chased by racoons that live in my barn, and I've accidentally picked up a possum when I thought it was a cat before.
Luckily I have a puppy now, and we haven't lost any chickens since she came. But I do have to put up with her barking all night long everynight. So I haven't decided if it was worth it yet. I'm pretty sleepy. lol
Again sorry for your loss, and I hope that you have luck with getting rid of the coon.
