The last I heard Texas still has the "horse law" on the books , use it .
Nothing deters a poacher better than making his life more important to him than stealing . Once a poacher turns up with extra holes in him the word gets around about "that place" pretty quickly .
You heard wrong. You use deadly force on someone commiting a property crime in the daytime and you are going to have a lot worse problems than some vandalized feeders.
BoBo, I do feel for you, it is damned frustrating. I have some property in Real County as well, right off Highway 41, about 12 miles west of Garvin's Store. I had some folks running four wheelers on my place. Never caught 'em, but did fence them out.
If it's locals, it could be happening any time, but if it is someone from town, it will probably happen on a weekend. Keep the Game Warden and County Sheriff aware of the problem, have them file a report for a paper trail. Try to fox 'em, and see if you can catch them, then call the DPS or County.
