I read that it is not a good idea to trap racoons. If you trap this one, you will soon have a new one take over in the same territory. It is much better to have a frustrated racoon that has given up on trying to get your chickens and turned to different food sources. Every new racoon will again try all the ways he can come up with until he has learned it is not possible, but eventually one of them might succeed...
Please allow me to school you on raccoon behavior, having had an abundance of experience working in state parks where these critters were quite capable of terrorizing humans in ways that you wouldn't believe. The bottom line is raccoons are thoroughly corrupted by contact with humans and will not revert to their previous innocence afterward. The only solution is to trap and exterminate.
The campground where I worked was plagued by raccoons slashing screens to get inside trailers and tents, and they raided campsites for any food they could locate. Entire families of 'coons were running like little street gangs through the campground, and the final straw was getting a report from a picnicker describing a raccoon climbing up his back as he sat eating at a table. He was startled even more when the raccoon reached over his shoulder and snatched the sandwich out of his hand.
I wasn't going to wait for a raccoon to injure a child snatching a cookie from her hand, so I convinced the higher-ups to allow me to trap the raccoons. I baited my "Have-a-Heart" traps with KFC (original recipe) and caught 16 raccoons over a three night period, adults as well as their juvenile offspring. The prisoners were then executed and fed to the coyotes several miles away from the campground.
There were the expected objections from soft-hearted animal lovers, but the end result was more dramatic than anyone could have predicted. Even I was a bit concerned that I might have decimated the raccoon population, but there seemed to be just as many raccoons sighted by park patrons as before. But here's the truly remarkable thing. None of them were exhibiting problem behavior. They were all going about their own private raccoon bidniss without being a menace to humans. It seems only the corrupted ones had been caught in the traps as they were the ones corrupted by humans feeding them human food.
This is as good a case as any for making certain that any raccoon that kills chickens is exterminated. The good raccoons aren't going to be hanging around humans, and no raccoon that has killed chickens once is going to voluntarily quit being a problem.
