Without a doubt they certainly are unusual looking chickens!
Their strange appearance, friendliness and mothering skills are surely what endears them to many folks.

I was friends with a Jesuit priest about 20 years ago that kept Silkies as pets. It was a little weird to be sitting out on his porch drinking beer and talking to him with all those little freaks climbing into his lap and competing with me for his attention.
What was really weird though was when he gave them their daily bath and blow dried them afterwards. They just sucked that shit up.
