Today I found my hen with a dead wing after it managed to jump and get caught in a high up, of rope that hung from the roof of the shed in a "u" shape. I found it hanging by both its wings, unable to reach the ground. It must have been up there for a few hours because when I got it down one of it's wings were swollen and red around the joints, and the wing was dead. I think there wasnt enough blood going to the wings because of how it was hung from the wings and the rope was pushing tightly up against the wing joints so it couldnt escape. Does anyone know if this will heal and if there are any treatments for this?
