While physically possible, throwing a rock at a drone is legally hazardous and potentially a federal crime in many jurisdictions. In the United States, the FAA classifies drones as "aircraft." Under 18 U.S. Code § 32, damaging or destroying an aircraft is a felony. Even if the drone is hovering over your private property, you generally do not have the right to use "self-help" force to down it. Doing so can lead to civil lawsuits for property damage and criminal charges for reckless endangerment, as a falling drone with lithium-polymer batteries poses a significant fire and impact risk to people on the ground. The legal recourse for a nuisance drone is to document the flight and report the pilot to local law enforcement or the FAA for violating privacy or airspace regulations, rather than engaging in physical retaliation.
