My chicken Clare is acting really weird and has runny white poop running down her butt. She's usually really peppy and won't leave me alone, but she isn't moving very fast and looks like she's in a lot of pain. Then, she'll crouch down like she's trying to lay an egg or maybe poop and screech. She hasn't started laying yet if that helps. This is Clare. She looks like she's in pain? This is the poop running down her butt.
