It's good that you caught the raccoon, those things are hard to keep out of a chicken coop.
Back when I was homesteading, I lost chickens to several different critters. Our problem was usually a skunk. I did catch one mangy coyote in the chicken coop with a double spring trap. I used the dead chicken as bait.
I found out the hard way that it's not a very good idea to shoot a skunk inside the chicken coop with a .410 shotgun. That coop stunk for weeks!
