Abma's Farm in Wyckoff was closed Monday for an investigation after a group of young people broke into the farm over the weekend and harassed the animals, according to authorities.

The farm posted about the incident on its Facebook page, writing in part, "The safety of our animals has been compromised and that is not OK. Our animals are now shaken and [skittish] compared to their normal relaxed nature. This is very troubling to us." The owners say that the animals were left skittish following the incident.

Police have been searching for the teens who trespassed Saturday night onto the property and climbed on some of the its animals. The animals were getting checked out by a veterinarian to make sure they are OK.

Officials say that at least one of trespassers climbed onto a miniature donkey and posted a photo on Snapchat. Veterinarians say small donkeys should not be carrying more than 50 pounds. The person who posted the photo tagged the Abma's Farm location, and that’s how the owners found out.

“Even though this is a petting zoo and we open it to the general public to enjoy it, this is still our backyard,” says Jimmy Abma. “This is still our family. We still have four families that live here, and it's no different than someone going to your home and wanting to mess with your dog or cat and wanting to mess with your cat and not really caring.”

The group of teens got away after breaking into the petting zoo. The owners say the safety of their animals has been compromised, and they wish the whole situation would have been avoided.

“If they came up and said something to us and said look I apologize how can we make it up, I don’t want this to happen again, it would have been an easier conversation, says Abma. “Now the fact that we have to go through all these avenues with the police department, they kind of cooked their own goose.”

The farm says this morning all of their animals have now been accounted for, but they're skittish. Abma Farms has close to 60 animals, including ducks, goats, pigs, rabbits, sheep, ponies and alpacas. Abma says he is still waiting for the veterinarian to come check out the animals. The petting zoo should be back open Tuesday as long as they're all OK.

Abma says police are working through a list of names that could be the suspects. Anyone with information is asked to contact police at (201) 891-2121.
