Kippen House Urban Chicken Coop & Planter. Our price: $1,250.00 This cleverly designed chicken coop has a built in planter box on the roof to maximize your urban gardening opportunity! In just a 20 square foot space you can grow vegetables and raise a few chickens to provide your own fresh eggs. (looks simple enough to DIY)
I'm thinking dog house instead. Back Yard Chicken Coop with roof garden, no reason why you can't use pallets for this project. However a word of caution,use heat treated pallets and not chemical treated ones as the chemicals do leach out and can cause problems for animals, birds and your chickens.
