These Tombstone ranchers need to use a little more imagination to deter the illegals. At night, when they're crossing over your property, have a half a dozen friends dress up in Chupacabra costumes, and scare the living daylights out of them until they run away.
Keep having the 'Chupacabras' appear until the word spreads that the goat suckers have taken over your property.....problem solved.
I don't know what the H-E-double hockey sticks a "chukacrkbka" is.
