OK, well i have domestic ducks and i was going to use them for eggs, but im just caught by how many species and how beautiful ornamental ducks are!! i want to build an aviary really bad!! I have a few questions though... 1. can i just get 2 or do i have to get more? 2. whats the smallest an aviary can be with a 4ft long 3ft wide pond in it? 3. whats the quietest ornamental duck that is still attractive? 4. what should i use for materials from building the aviary to substrate for the nesting boxes and ground? 5. whats a cheap way to keep a pond clean for the ducks? 6. are ornamentals less messy than domestic ducks? 7. will they eat plants and grass that i put into the aviary? 8. whats your favorite ornamental duck?!?!?!?!?!
