Chicken monster

Well we went to the local animal shelter and picked up a trap for whatever is scratching at the chicken coop at night. Whatever it was, it came out two nights in a row and made me nervous so I decided to see if we could trap it. I sent the trap up for 4 nights in a row with a yummy stinky tuna bait. Nothing. I think it was a Possum, we've been seeing alot of those guys lately. The scratch marks didn't belong to a cat and a Raccoon would have just unlocked the door! But don't think I've given up, I'm sleeping with one eye open.
