I have been raising my two wood ducks in an outdoor aviary I got from Cagesbydesign.com. It's the 10 foot diameter cage with the safety box attached. I put a 5 foot diameter galvanized stock tank in side the cage that's 1 foot high that I purchased from a grain store. I use the repile ledges found on Cagesbydesign's website for the perches. The wood ducks like to fly up and perch on them. I also provided a wood duck nesting box and the 1st year that I had these ducks, they produced 15 babies and since the young are in a protective aviary/cage, all lived without predation til they were able to fly. The babies have since flown the coop but the original two woodies that were hatched and imprinted to the family are kept inside the aviary as ornamental birds.
