I am not sure what is under the chick other than the shavings but I think they are supposed to be on something more grippy so their legs hold them.. I have also been told not to put shavings down until after the chick is over 3 days and knows what its food is. They mistake the shavings for feed and it can cause problems in the digestive tract.
Read this and try it. The sooner it is done the better the outcome. Remove the shavings and cover the floor with paper towels or other absorbent, but non stick material. I like the puffy vinyl shelf liner. It gives them good traction and prevents slipping.
Also there is a post on here somewhere about putting the chick in a glass with a narrow bottom to force the legs into the down position. It is also supposed to help strengthen the legs because they push against the bottom trying to get out. make sure to put paper towel in the bottom of the glass for traction.
