I have a 5 day old chick that cant seem to get its feet under itself. When standing the back half sags making it difficult to walk. She gets knocked over and has difficulty righting herself. There is no visible injury. Hard to know if it came out like this or got trampled by the 16 other hatch mates or the Mama. Is there anything I can do to help this little one out? She hatched unassisted on 11/28 or 29.
