I had to choose Polish. By far. I've owned most of the breeds listed here, and what others have listed. But when my polish died, I cried.
The fact that they are partially blinded by their crest means they will either trust you, or they won't. And if they get to the point of trusting you, they are SO friendly. Mine liked to stand on my feet when I was around. They would always come when I called them (and noise was one of their ways of finding me) and used me for protection from the roosters, sometimes.
But unfortunately, that inability to see became the undoing of my last two. One was somewhat crushed by my biggest roo (even though she was large fowl, she was still somewhat young) and the break was SO high and SO messy that there was no way it could be fixed. And the other was attacked the very next night by a raccoon.
I've never cried over a lost chicken until I lost those two. Now their roo is lonely, but I couldn't possibly live without the breed, so he's got six girls coming to him this spring!
