Attack in the Night

No matter how "coon proof" one may believe an enterprise to be, we still get the occasional surprise. A couple months ago, when our cornish rocks (meat birds) were just 2 weeks old, one was injured while moving the pen across the concrete into the grass. I cleaned her up, bandaged her little foot as best as I could, and kept her separated until she was well enough to hold her own with the others. When we she re-introduced, she did fine and after only a couple days, I could no longer tell her apart from the others.
Until 2 days ago when I noticed one with a stubby toe laying down a lot. This tends to happen sooner or later because these birds are huge and bred to be quite lazy. But she was laying down and letting other birds walk on her. Yesterday I pulled her out, made our makeshift hospital pen with the baby gates and plywood and kept a close eye on her. We're slaughtering our turkeys in a week (obviously) so if need be, we could slaughter her at the same time. Though I'd rather see her healed and strong and live out her days happily scratching and clucking.
Her "hospital" was under our bedroom window and long about 3am, we heard the screaming. I flew out of bed and chased off a rather large and portly racoon. He had dug under the gate and managed to grab her neck. She was scratched, but alive. I re-inforced the pen, moving the duck baths to block direct contact with the ground beside the gate and added some rubber floor mats to keep her away from the edges. The coon came back around twice more, no doubt scaring her out of her wits, before giving up. She's hurt... pretty bad too. I think she's going to survive as long as I can keep her safe, but unfortunately, I don't think she'll heal up well enough to become a full-grown bird.
It bothers me when I'm not able to keep my animals safe. Just last week, 4 plymoth rocks (young egg layers) died in a single night. They had climbed inside the feeder... and then a cornish rock climbed in on top of them. The cornish, though the same age as the plymoths, are much bigger and the 4 little ones were suffocated. I think the hardest part of homesteading is dealing with accidental deaths. Slaughtering animals and finding one dead before its time are completely different experiences.
