She's a Blue Orpington hen, I'm not sure exactly how old she is. I got her in June, was told two years at the time.. She's been not quite right for a few weeks, not laying, not looking healthy, slightly subdued..not her former self. She's going through a really bad molt, and insult to injury, she is also my 23 week old Rooster's favorite hen, since there are only two hens of mature age in my flock, and the other one kicks his @** if he tries anything with her. Her comb and wattles are pale-ish and look chewed up by the roo, her comb is actually folded over to one side. Two nights ago, I was doing the headcount in the coop before I locked everyone up and she fell (was pushed!) off the perch. She landed belly down on the floor, a fall of about 4 feet, and started flailing and squawking, unable to straighten out her neck. It was flipped over backwards if that makes sense, not turned, but actually folded over backward. Once I realized what was going on, I straightened out her neck, and put her in a quiet, uncrowded space on a lower level shelf in the coop. She seemed a bit disoriented, but quieted right down once her neck was going the right way. I was sure she'd be dead in the morning when I let them out, but she hopped right out and started doing what chickens do with the rest of them. It happened again today in the run, I was sitting in there, tossing mealworms, getting my afternoon entertainment and all of a sudden, I hear her squawking, her neck is flipped backward again and she's freaking out. I straightened it out, she went back to chasing mealworms. Could this be due to an injury? Can she get better, or should I put her down?
