What are the damnation's of the nest boxes and how big of a hole??? any one can answer.I need a wider angle lens for the pictures and then I would not have had to take so many to try and convey the look of the aviary. Basically I built a 135' x 85' pen with 10' sides and 12'-14' tall center posts. I have a pond that is about 3'-4' deep that is fed from a well 12 hours a day using a 1 1/2 hp submersible well pump. All over flow goes back into the 3 acre pond located adjacent to the aviary. I also built a 25' x 66' pen on the back side of the main aviary for housing birds that are for sale and the flock of Cochin/Silkie Bantam mixes that I use for egg incubation. The one main improvement that is going to be expensive is that I plan on building a retaining wall that goes right up to the front of the aviary so that when people visit they will have ducks swimming in front of them at about waist level and 2' away. I also use cypress wood for all of my boxes and actually had most of them built for me by Heath Brinson in Mississippi.
