I would suggest that you post in here:Help me my chick is in pain

They'll need a lot more detail to offer any advice - age of the chick, diet, housing, symptoms, even the kind of chick can make a difference. For instance, I had a chick hatch that I thought had spraddle legs, only to find out that in the Silkies or other short legged breeds it's not unusual for them to take a day or so to get their feet under them. Good luck!!
