In all, two thousand mink were released.
The good news for the Bonlander Furs farm is more than 80 percent of the mink have been found and returned home.
They say it could not have happened without the help of friends and neighbors.
"People came from all over the state, all the other ranchers their friends they spend the whole day here Saturday" explains Joe Bonlander, whose family owns the farm.
Since 1978 the Bonlander family has raised mink.
"A mink farm is a business, it is a livelihood, there is a lot of work involved" explains one of the co-owners Virginia Bonlander.
Vandals opened the cages over the weekend to release two thousand mink.
They allowed about $300,000 worth of sales to run away.
"Chances are they will not survive in the wild because they are not a wild animal" Joe explains. "They are not bred or born in the wild, they are a domesticated animal".
About half of the mink were ready for harvest before they were released.
Now they are mixed in with younger mink, which will be a labor intensive process to sort out.
"When we caught them we put them in an open cage, then we put another one in and it is not their original partner. Some mink do not get along" Virginia says.
The Bonlander family believes animal rights activists are behind the release.
"I believe they did do more harm than good to these animals" says Joe.
"We did not have any security around here, but there will be now" Virginia says.
The Calumet County Sheriff's Office is asking anyone with information to give them a call at (920)849-2335. The FBI is also involved in the investigation.
