Very intriguing idea, and I hope you find it to share with us, too.
Meanwhile, this may give you some ideas:

Their "garden pool" made from an old swimming pool provides:
* solar power harnessing and storing the suns energy
* water conservation using less water and recycling waste water
* poultry farming raising chickens
* aquaculture raising tilapia fish
* hydroponic gardening growing fruits, veggies, & herbs without soil
* organic horticulture using natural methods to control garden pests
* aquaponics the symbiotic cultivation of produce and fish in a recirculating hydroponic environment
* biofiltration natural water filtration method using biochemistry and duckweed
Just find a cottage-style coop you like and work it into their design.
