Soon ill be building a new duck aviary I WANT it to be 50"x100" with a 45x45 pond but my dad says other wise. He wants me to build a 50"x50" pen with a 45"x25" pond this was a major downer. If I end up having to build it so small how many ducks could I house in their ill also be letting the mothers do most of the child rearing (except maybe for the wood ducks)
