Having livestock on the farm yes it's legal to shoot "animals" even out of season if they are destroying your goods and profit, so consider yourself a animal if I ever find you past dark on my land, multiple trespassing signs and fencing should give you a fair warning.
Don't have any neighbours within 3+miles, if someone's on my land it's for a reason, I try to give them the benefit of the doubt, no hunting/trespassing signs don't always make sense in people minds until they hear a shot go off and 3 German sheppards chasing after them
happy smoking
