I had a SL Polish chick hatch with a slight prolapse.... I knew something was wrong as it took an awful long time for it to zip.... Also its leg has a constant shake, and seems to not be able to hold its head up as a chick would usually, like it has another problem, I know they cannot usually hold their heads up, but its hard to explain its trying to walk about, but its head is on a constant wobble, and looks a little like maybe wry neck?? but not twsted as much... what should I do???
