When our neighbors got chickens, our other neighbor got very upset because they were letting them free range and they were getting on their property. I happen to agree with them that if they don't want the chickens on their lawn, they shouldn't ben there. The way our property lies, our chickens have stayed on our property so far, no problems, so they were never upset with us and it hasn't been a problem. We have a fairly large property, as well. But here's the part I find a bit hypocritical. They have a big cat. Big cat regularly prowls in our woods. Big cat pees all over our back yard. A few days ago, within an hour of letting out the girls to free range a bit, during the brood daylight, we lost a young bird (about 2 1/2 months) I am pretty sure to Big cat. If our little ones were bigger, they would probably have no problems defending themselves from Big cat. Not sure what Sir, our useless roo was doing at the time, unless he was rounding up as many as he could, but I found all the other girls squeezed into the kitty litter pan I bought for a dust bath in the coop. I realize that occasional loss is part of free ranging, but to a roaming cat? Should I say anything to them? Yes, no? FWIW, the bird was killed very far into our property line.
