UPDATE/NEW PROBLEM:
Just in case you were curious, the raccoon didn't take any more chickens that night. Probably was full from the one he ate. Or leaving the radio on might have helped.
I see the error of throwing the dead chicken into the bushes (though it was done in a panic). The raccoon didn't take any more but the feathers/chicken pieces are spread around 1/2 acre and I'm having trouble picking them all up.
We went that morning and got the tiniest metal hardware cloth and wrapped the chain link with it, from the inside of the run. 3 feet high and it seems pretty sturdy. The raccoon came back that night (last night), a few times, I heard one of the chickens running around but it wasn't able to get her b/c of the new mesh. Ha! It did manage to keep me up all night and make me madder.
A friend came over and let us borrow a trap which we will set up tonight. Hate to do it, but the friend volunteered to pick up the full trap and take it from there, which I really really appreciate.
My new problem is the smell. I gag when I go out there, I think whatever blood was spilled has gone rancid and I don't know what to do about it. I've picked up all the feathers I could see and bleached down all the metal surfaces, posts, etc. But how do I get the smell out of the dirt???
Any suggestions would be SOOO appreciated. Next step: secure inner coup that they can be locked in at night. Final step: electric fencing.
