Saw my first predator yesterday - an opossum. Thankfully it was a small one, and ran away when I walked toward it. But the bad news is that it was IN the chicken run that I didn't think it should have been able to get in to. It ran around the side of the coop and was gone before I got there, so I did not see how it left the run, either.
So - how do opossoms get in somewhere that would be difficult for them? Are they climbers, diggers, push-their-way-in animals, etc?
And out of curiousity, how large would an opossum have to be to really be a threat to almost-grown chickens? Mine are Cornish X, 6 weeks, so about 6 lbs apiece - they look almost full grown. This opossum was small, I probably could have turned a bread pan over on top of him, including almost all his tail. I'm wondering if he's an active predator at that size, or if he was just looking to see if the chickens left any good food around?
Any info you can share about opossoms would be great, thanks! I want to get rid of this one before he gets any bigger.
