I've had 3 incubated chicks do this to me at around the 2.5 week mark. She is relatively quiet now, normally the crying is really really loud. It almost seems like she cannot see, though it may be just really painful/uncomfortable. No accident or injuries just starts off with her putting her wings out, crying loud, crouching while walking, being generally uncomfortable (wont eat or drink during episode). I would hate to think it is something we are doing wrong. She hangs out on old (clean) blankets off the floor (on my bed lol)with a clear heat bulb during the day and once in brooder a red bulb.
