I bought a huge aviary off trademe, but its gonna need a big upgrade to make it weather proof for my budgies.
I intend to cover the roof with clear corrugated roofing, plywood the back and maybe add some form of insulation behind the plywood.
If you are aviary savvy, any advice would be much appreciated.

It is in 3 sections at this stage, with a door into each. 5m wide. 1.8m deep. 2.35m high.
