(Not sure if I posted this in the right place) My chicken is sticking her leg out straight behind her when she walks, drooping her wing towards that leg, acting lethargic and resting on the curled toes of that foot... but only at night! This has been going on for the past 2 nights and she's perfectly fine during the day, scratching, eating drinking, ect. She also has trouble balancing at night I had to put her in the nest box to sleep. It seems she's worse tonight than she was last. Any help would be greatly apprieciated!
