What is wrong with Millie? My Buff Orpington Bantum Millie is acting kind of strange today. She keeps dropping her head to the ground as though it is too heavy for her. She is eating and drinking, her vent is clear and her poo is solid. What is wrong with her. It was cold at the weekend but they have plenty of shelter and places to run too as they free roam in the garden and are locked up in their Penthouse at night.
