This hen seems to be falling over each time she goes to scratch. I only have one instance on the video but it seems to be continual. She seems to be twisting her neck quite a bit not much. Mostly it is scratching vigorously to her right side then falling over. She did lay a shelless egg yesterday. Brought her inside because she seemed listless but she was back to normal after the egg passed. Any help would be appreciated. Thank you.
