Sadly, she had been dead for awhile before I found her. Even if I had found her alive, her ankle was snapped in the tangle and I would have had to kill her anyway. Poor thing. Hanging upside down isn't the kindest death.
Farmers seem to prefer fencing with two top strands of barbed wire; it keeps cattle from leaning over the fences, weakening or breaking the posts, and creating repairs that cost farmers time and money. I understand that. However, we are finding two or three deer every year hung up in fences like this. The deer attempts to jump, catches a toe on the top strand of wire, which bends and traps their foot, or feet, between the wire and the sheep netting.
We're doing our best to keep the deer numbers in check, so the deer aren't pressured to move all the time and forced to cross fences. It helps somewhat, but certainly doesn't solve the problem. In this case, wildlife loses out to farming.
I wish I had a solution that made everyone happy, including the deer.
