I hatched this chick in an incubator, but unfortunately, it's unable to stand up or lift its body. I've tried various methods, like taping its fingers to improve grip and keeping its toes in the right position, but it hasn't made any difference. It keeps falling to the ground and struggling to stand up. I suspect there might be an issue with its knee, but I'm not certain. Could you provide any insights into what might be causing this problem and what the recommended treatment would be in this case?
