Hello,

I live in an area with foxes and the occasional bear in our apple tree.  I want to put a large walk in pen inside a very large wire & electric fenced area, with 2 livestock dogs.  Should I also put the Cube inside the walk in run? or would it be safe to have the Cube attached outside the pen?  Any predator will have to get through the electric fence, wire fence, and past my 2 guard dogs... I plan on letting them free range with the dogs a couple hours a day once the dogs (anatolian shepherds) are trained properly as chicken keepers  Thank you!
