I always thought about why they used a Rooster template for a weathervane. Like Einstein and Newton I am frequently absorbed in such heady activity. After looking at a few other examples in common usage, I quit wondering. I have come to believe the Rooster might be the best weathervane of all. There are certainly animals that are not in the running at all. Now I wonder why anyone would use them. By the way, if I forget to give notice. Any pictures here that don't involve an actual live chicken were courtesy of google earth. I certainly wouldn't have them at my place and really don't know where you would go to find them.
When it comes to unsuitability as a weathervane this might be where it really lives. Other than possibly the ears I can think of nothing here that the wind will move. It's also pretty hard to see this as normal on the top of a barn. I have only seen one (courtesy of Disney) that flew.
On the other hand this fearless noble creature looks right at home soaring with the eagles. Actually it probably would intentionally avoid eagles.
You might wonder why a chicken would pick such a place to sleep. If you want a detailed answer don't ask a chicken. Ask a Raccoon.
On top of a roof? Really? That's a pretty long and tiring climb.
They once had a chicken house but a raccoon breached the defenses. They wouldn't go back and I couldn't blame them.
We find them everywhere. That isn't as problematic as finding the eggs can turn out to be.
You have to hand it to Elvis (the rooster, not the singer). Any reasonable person is going to recognize him as a regal beast deserving of recognition. The following pictures all came courtesy of google advanced image search. Very few of them actually live in high places.
In the meantime, Elvis here deserves his own template.
