Mad Cows
Unfortunately your cows have been infected by a strange disease....find them and put them down.
It’s sad but true: your cows have been infected by a strange disease. They are getting mad. Your only chance is to pick out the infected animals and get rid of them. You have 60 seconds to find 30 mad cows. Note: A healthy cow is behaving exactly like a cow should do. So avoid these as it'll cost you 10 seconds off the clock for putting a healthy cow down.
