My Shepherd/Collie mix managed to escape her enclosure the other day and went on a rampage chasing my poor chickens. She pulled some tail feathers out of two hens and I suspect she may have injured the one this post is about. I first noticed this hen's strange posture when I was feeding them. She emerged from under the front porch very cautiously, with her neck stretched far out. When she straightened up, she was walking taller than the other hens, with her neck still stretched oddly. She looked like this: I'm terrible at taking photos (they are always blurry) but I might try to get some of her later. Anyways, it almost looks like she's trying to walk upright (like a person) but with her neck stretched out toward the ground. It's very odd looking. I picked her up and she doesn't seem to be in any pain, and I didn't notice any obvious injuries other than her hunched back. I'm still not sure whether this injury is due to the dog, or something else. I don't want to cull her, but I don't want her to be in pain either. Any advice would be really appreciated!
