Don't have them, don't want them. Personally I don't like the look. They look messy and unnatural. My chickens are pets and hop into my lap, so I don't want to deal with dirty/poopy feathers bringing extra filth into my lap. I also live in a cold climate and don't want the added risk of ice lingering on their feet. I don't want to deal with the other chickens picking on the feathered feet, because chickens are dumb racists and will totally do that to someone who looks different

I also don't like it when people stray too far from what nature and evolution intended, just for the sake of human amusement. So I don't like chickens with feathered feet, frizzled feathers, top knots that obscure their vision, or other aesthetic human whims that compromise the bird in some way just for the look.
