We woke up to a racket in the coop and when I went out to see what it was I found one of our hens ( all mixed breeds) on the floor not moving. They sleep up on box about 3 1/2 feet off the ground and since she was the only one on the ground I assume she fell off. She was on her side not moving(looked like when they take a dirt bath) but didn't move when I wen to pick her up. She can't hold her knec or stand, but can flap her wings. She is in a small carrier downstairs in the dark in an unused bathroom for now. Any Ideas or suggestions?
