So we let our chickens free range and so does the neighbor across the street 2 house down. Well her rooster has been coming over and my hens are folling him across the street back to there house and a few days ago I ran out there because I heard a chicken squawking and he attacked one of my 3 month old chickens. I talked to the neighbor and told her and she said she would lock them up but it’s been a few days and the 2 are still coming over. I’ve shot them with BB guns and chased them off like 4 times a day. Would I be in legal rights to kill them? Or is there someone I should call. I live in Indiana I can’t find anything on the laws if I could be charged for it. This has been going on for months now
