His back pasture used to be used for raising miniature goats, so yes the whole thing is fenced with chicken wire all the way around.
While that was nice I still had my guy on a hugely long horse lunge line. My little guy knows come.. sometimes, but not well enough for me to trust him completely off-lead in that large of an area, its about..18 acres? Since their youngest boy is too old for 4H projects they sold off the goats and cows. now the field is just used for some hunting. They raise some of their own game birds like cotornix quail and chuckars. And well, the rabbits (wild) are all over that back field. I let my little guy "hunt" a few of them, never let him get one though.
and if anyone can let loose their B with a rock solid come, they need to fill us all in.
