If it was left up to me, the people or person who did this would receive the same type of pain and agony that these ducks received! This just infuriates me! 
CEDAR RAPIDS, Iowa -- Cedar Rapids police said 52 ducks were killed at a park exhibit overnight.
Workers said the ducks were fine and locked in their cages when they left the Schucknecht Exhibit in Bever Park Children's Zoo around 6:30 p.m.
By 7 a.m. on Wednesday, workers returned to find all of the ducks dead.
The dead ducks were found floating in two ponds when an employee went to give them their scheduled feeding. Close to 40 ducks weren't hurt.
Police said the vandals broke locks on the bird cages and then chased the ducks into the pond and threw grapefruit-sized rocks at them.
Cedar Rapids police are asking for the public's help to track down the person or people responsible. Anyone with information is urged to call 319-286-5440 between 8 a.m. and 4 p.m.
The case remains under investigation.
