I have an 8 week old chicken who has always been smaller than the rest, but she seems to eat and drink fine. We put them in their outside coop a week ago and found her in their run last night. She is extremely wobbly when she tries to walk, and eventually just sits down and stays put. Last night she fell on her side while trying to walk and could barely roll over. She seems very weak. Her droppings look normal and she's eating and drinking. We moved her to a crate in our house. Does anyone have any suggestions?
