That they can be.I used to keep my bucks in a place called the OK corral because there were so many boards and branches nailed to trees, over top of cattle panels, plus a hot wire. Those males can be very persistent.
You could build a small enclosure of t posts and cattle panels and put a small 4x4 shelter in there. I had one i used for a quarantine/ sick pen. And i had one to put goats in that were sold so i didn't have to catch them later.
We already used all the cattle panels and T posts on the farrowing pens
