One of my 5 week old cochin mix breed is missing today. I spend at least 3 hours searching for it around the house and on the street, but I can't find it. My mom told me that one of our neighbor, is complaining about them going into their lot and eating their plant's leaves and making poop. However, I only saw 2 groups of my chickens going there this year. One group consists of 2 chickens and they went maybe on january or february and the other group which is made out of 5 chickens went there yesterday. Last year only one group went in there once or twice. Interestingly, whenever they go in there, they don't know how to come back. So, I know, that they rarely go in there. However, they might go to their property near the sidewalk a lot of times(but I doubt that they go in there a lot of times), but there are no plants near that place.I saw a lot of wild birds going into their property everyday, so they might mistake their poop as chicken poop. Another neighbor, also captures stray chickens( not my chicken) and eat them. My neighbor that captures and eat chickens, had a dog last year which enters our property, and chased my chickens a lot of times. However, I didn't do anything to the dog, except chase it, to make it go away. My chickens are free range everyday, and most of the time, I let my chickens out of their cage and coop after I wake up, because I want them to be happy. Do they have the right to kill my chickens if it makes poop on their property and eat some of the leaves of their plants(they didn't kill the plant and it will regrow)?
