In farm country, the reaction to Potter's scheme has been mixed.

Emily Meredith, a spokeswoman for Animal Agriculture Alliance, a livestock industry group, is critical of Potter's plan.

"It's unfortunate that the media and others see Mr. Potter and other detractors and activists as having more expertise than the folks with their boots on the ground every day, growing and raising our food," she says. "It's even more unfortunate that people contribute to campaigns like this on Kickstarter instead of investing in any of the other myriad of worthy causes — including working to end hunger."

Others are warning Potter that the drones could be used for target practice.

"Those things better not be coming over during duck season because there are hunters out there that might look up and mistake that drone for a duck," says Chuck Jolley, a meat industry veteran.

Jolley, based in Kansas City, Mo., has disparaged ag-gag laws and argues that farmers and ranchers should open their doors to anyone who wants to see their operations. Jolley's not alone; Temple Grandin, the animal scientist at Colorado State, has advocated for placing video cameras in slaughterhouses and livestreaming the production lines.

But many in the animal agriculture community oppose the recent investigations by activists, and support laws that give producers the power to sue them for trespassing, invasion of privacy or harassment. Commenters on Jolley's recent piece for Drovers CattleNetwork called the animal rights activists "terrorists" and "zealots" who don't understand agriculture and edit the videos selectively for maximum dramatic effect.

Could Potter be prosecuted for flying drones over farms? Clemens Kochinke, a Washington D.C.-based lawyer behind the Drone Law blog, says the law is unclear about monitoring ag businesses. And it takes years to test the laws in court.

"Aside from the many federal issues involving the [Federal Aviation Administration] and the [Department of] Homeland Security, you have the state, county and municipal rules," Kochinke says. "An overriding limitation on the restriction of drones may derive from the First Amendment where reporting in the public interest is concerned."

In an interview, Potter told us he will focus on the states where anti-whistleblower laws are being debated. He pledges to share his findings in an e-book and a short documentary.

But Potter admits the drones he plans to deploy won't be able to get the same, close-up footage of livestock operations that groups like Mercy for Animals and the Humane Society obtained through undercover investigations. Instead, he says, he'll focus on showing the magnitude of the operations and the pollution they generate.

This is not the first time activists have deployed drones to investigate animal issues. In April 2013, PETA, the animal rights group, announced it would be flying drones to "stalk hunters" and "monitor those who are out in the woods with death on their minds."

At the time, farm country and hunters went on defense, suggesting the PETA drones would be a "trophy prize." Ammoland.com, which publishes shooting sports news and advocacy, published a printable target its readers could use for practice, complete with a PETA logo with its bunny.

Since then, PETA has begun selling its Air Angels Drones to the public for $329.99 each through its online catalog. So far, PETA has sold more than 60 of the aircraft; the suggested use is for watching wildlife and looking out for illegal hunting, says Lindsay Rajt, PETA's associate director of campaigns. Using new technologies to advocate for animals is part of a "compassionate trend," she adds.

Ingrid Newkirk, PETA's president, says she's supportive of other people using drones to gain information that may help prevent animal suffering. "If Will Potter uses drones legally to shine a spotlight on factory farming and slaughter practices, we're all in favor of it," she says.
