I have 4 newly hatched chicks as of yesterday, but 1 of the 4 stands straight up all the time. Like not only is it standing up all the time it stands much more straight than the other chicks. It will not squat its legs to lay down on its tummy like the rest of the chicks. I have caught it kind of sitting back on its bottom a couple of times but never laying. It was one that did need assistance with hatching because it was malpositioned inside the egg. But the assisted hatch was fine and it acted normal up until it dried off and started learning to use its legs. I just held it supine to see if the legs would naturally retract to the stomach and it did it naturally. I have never seen this before. I wondered if being stuck in a strange position inside the egg for so long had anything to do with it? Any ideas?
