RE: Is this legal
It is absolutely illegal.
When you fence a property you have to buy the deer that may incidentally been " trapped" inside from the PAGC and that is assumed by the deer denisity of the area you fenced...I believe the cost of $100 per deer....This is what I heard from a recently fenced area and could be somewhat misinterpreted.
To fence an area, bait into it wild animals and then hunting them, without said permits and purchases of said deer, and I doubt these people have either, not only are they breaking the law, they are pathetic in terms of hunting, sportsmanship, woodsmanship and ethics.....[:' (]
