I have a chicken that is 4-5 months old....she acts perfectly normal, eats, drinks, poops...the problem...she can't get her balance. She has strength in her legs, her claws wrap around my finger...this has been going on for 5 days.....if I put her out in the yard, she either lays there and looks around or tries to move, but just can't get upright.....I would appreciate any input...I have thought about putting her down, but with her acting normal, I keep hesitating......Thank you for any help..
