I can’t remember what it is that sheep won’t eat - but I do know (remember) - even if the gate is left open, if the head sheep doesn’t realize it - they won’t leave the pen.
Goats will eat anything - including soft tops of cars (never put a goat in a garage!?!)
Horses won’t eat weeds.
But any of the grazing animals will eat wood/bark - if they are deprived of food too long.
Probably helps the eco system reboot in really bad drought/cold years.
Just like wildfires.
And apparently a drug dealer/mule had been using a tad of his/her merchandise that they would dump it inside a fenced area (implying a farm of some sort) probably when being chased by the local LEOs or another incensed dealer/mule or they might even have been attempting to score a big sale for themselves and blew it (so to speak).
Obviously usage does impair some people beyond the munchies.
"Fanny’s farm”....snigger
Happy Sheep!
