Hi! We have a 1.5 year old khaki campbell female who we are noticing is acting strange. She is randomly sitting as she walks around, and when she sits she picks her legs up and kind of stretches them. When we just gave them lettuce she even sat down to eat. She is laying, drinking, eating, cleaning, and happily snacking. I've just never seem her do this. I checked her feet, no scratches or bumblefoot. Does anyone know what could be wrong?
