Yes it is a gentic default to be exact. They have a resessive gene that is not good for the deer herd. The law in Michigan's case, was passed because a Senator was feeding one and someone shot it! People in high places have pull, politics at it's best. This law was passed on emotion and not fact. Even the DNR biologist say these animals should be removed from the herd. The law passed in 1979 has been in effect since, crazy law. This is another fine example of how our DNR is managing our deer herd. Fact is Fact................. Emotion is Emotion.......................
And the Law is the Law.

This is Michigans Law on the Subject
