Hello everyone! I just went outside to let my chickens out and I noticed something hanging from one hens vent. It's quite long, about 4-6 inches. The bottom is dark I think because it has been touching the dirt and mud. However, the part closest to her vent is a color between a creamy yellow and white. She doesn't seem very comfortable, as she's only walking upright and doesn't seem to be able to crouch down. Does anyone know what this is or what happened?
