Goats for land clearing

I have 70 acres with tons of brush and honeysuckle. My thought is to get a goat or two (preferably not male/female; don't want to have to mess with birthing them...) with the NoFence collar to eat through the 70 acres. There's water on the property (creek) and a shelter can be provided.

What advice/concerns do you all have with this idea?

Thanks
