A natural, fire-proof, fool-proof way to keep your flock warm! Just bringing a little levity to the debate about heating the coop... Unfortunately, these poor New Zealand penguins have been contaminated by an oil spill and to keep them warm and keep them from preening themselves, (they are contaminated with toxins), kind volunteers have knitted them these very stylish sweaters. They seem quite happy in them! I could definitely see my girls sporting this look!
