About a month ago I caught a raccoon after I noticed fish guts were dug up from the mulch pile. I set a trap and made the mistake of letting it go, because I figured my set up was strong enough, it had also dug up dead chickens from a dog attack a week before. Then 4 days later I catch a baby so now I'm afraid they will open my barn doors that my coop is inside, we have 4 door to the barn with the same twist latches. I bent nails to put in were the lock goes. It would be too much of a hassle for locks so are carabiners coon proof? Inside the barn It would be easy for a coon to get into the coop, I have open vents on the top and a chicken wire door that one could easily break/crawl through, the barn is solid other than the doors.
