A brief post-script to my previous post about the neighbor's dog, which had broken in and killed several of our chickens:
Things seem to be going better. The boy's parents came over that same night, introduced themselves, and apologized profusely on the boy's behalf. The boy himself came over the next night and also apologized; all three of them assured me they'd be keeping the dog tied up during daylight hours, when our chickens are out. So far, we haven't seen the dog again. I've heard him howling a bit in protest, but it sure beats hearing chickens squawking in panic.
The kid has his own landscaping/snow removal business. Friday night, we got a couple of inches of snow. After apologizing for his dog's behavior, he jumped in his truck, lowered the snowplow, and cleared our entire driveway and parking area. This was an enormous help for us, as our driveway is quite long.
So...it's unfortunate we had to get off on the wrong foot with our neighbors, but hopefully everything's on track now.
