DIY Basics, these things are expensive, Do it Right the First Time!
One should create a list of requirements for large outdoor Aviary as once they are in place, common one is very limited in make changes.
Having correctly (safely) installed electrical for lighting and support outlets. And yes, they are located away from where the Parrots have access.
- Why lighting -- you will leave your beloved Parrot outside in the dark and you will get an uninvited guess at night. So plan to be able to turn the lights on /off from inside. Having available support outlets will simplify cleaning and repair projects.
Having a safe water source is important!
- Cleaning, misting, etc...
- Drainable during cool and freezing.
Water drainage away from the large outdoor Aviary is very important!
Things like to live in Parrot Poop so it is important to be able to wash it clean from the interior area of the Aviary.
Hard surface (like poured concrete) helps in assuring a full and clean wash of the area.
Set the hard surface so that it extends a bit beyond the side structures.
Strongly consider a double door, enter the first, close it behind you and check the area then enter the interior door.
Locking outer door! You will be surprised at who you may find inside your Aviary!
Shaded area and covered area. Near all Parrots love Sunshine, and just as many love being able to get out of it into the shade.
Most side walls and tops are constructed from square steel tube and either square or rectangle steel mesh and then coated. I strongly recommend Powder Coated System. The metal parts can be found on the open market, or built to your specification by a local welding shop and the Powder Coating System by a local shop that does such work.
Paint will rust and flake and that can become a problem as most Parrots will try to eat it.
NOTE: Assure that your Parrot's head will not fit between the mesh...
Enjoy!
