No need, Jack, we have all had dead chicks at one time or another. If there is no chance of cocci (you would see bloody poo) it is likely stress. Make sure to keep them warm (95o) and keep their bedding clean and dry. I would give them some boiled egg yolk. You may add plain yogurt, tuna, or cat food. Your chick likely died of stress or trauma from the shipment (these are shipped chicks, right?) Poly Vi Sol without iron may help. If you have one that looks bad, try a couple of drops of sugar water. All of this is just to support them until they recover from the trip.
