Starting with a dog house kit (or even just a dog house) is a great time-saver! The instructions are clear and well-supported by clear photos of happy ducks. The notes on adaptations, like the porch-painted interior, and the "what-I-would-do-differently-next-time" comments are especially helpful. This is a simple, efficient, very good-looking poultry house.
Note for chicken owners - use a different wood for chicken coops, as cedar is toxic to chickens. Not only will it keep your chickens healthier, but it will save you some money!
