Other than putting a KFC on the other side?
Ok, serious (well, sincere at least) question here:
There’s a restaurant in the Shirogane neighborhood of downtown Tokyo called Blue Point (website’s in Japanese, but it has a map if any Tokyo dopers want to go see for themselves) that, aside from being fairly upscale and expensive, is also notable for having animals all over the place. Walking by, I’ve seen several large fish tanks and a rabbit hutch, and customers often have their dogs with them. The most unusual sight, though, are the chickens wandering loose around the patio cafe. I’ve seen three adults in the past, and just last week I saw a hen with three chicks.
Now, this patio cafe is right on the sidewalk next to a fairly busy street, and while the chickens are usually roaming the sidewalk freely, I’ve never seen them go out into the street. The sidewalk has a small hedge on the street side with an ironwork railing to protect it from parking cars, but the hedge is fairly open near the bottom (the chickens are often under there scratching around), and the railing doesn’t seem to be any kind of barrier.
So what’s keeping these chickens where they belong? They seem better trained than most dogs or small children.
