I bet they gave you the wrong DE I would remove it right away.  Food Grade DE should not do that.  You can call them and ask them what the label reads.  I give mine DE all the time and have it sprinkled in their nest boxes and hen house and never had a prob with it at all.  I also sprinkle it in their food.
