You've seen chickens before, but have you ever seen a white crested black Polish chicken? Think in terms of the Muppet Big Bird, shrunk down to chicken size but twice as strange. Maybe three times. Another chicken that might set you back apace if you haven't seen one before is the mottled houdan. We can't really describe it, but you can see these and a wonderful variety of regular old chickens, geese, turkeys, ducks and game birds just by walking through the Fur & Feather Building on the weekend of the big Pan Am Poultry Show at the Texas State Fair. Fur & Feather is where the contestants all bed down between appearances. It's open to the public. Be prepared for random loud outbursts of gobbling.
