I would be careful with bird netting! Depending on what kind of "netting" you are thinking of. If I was you I'd use wire mesh or something else sturdy.
When my husband and I first built the aviary, which is a room with windows on 3 sides, we didn't want to keep the big windows completely open for fear that the birds might bump against them thinking they can fly through. So we used bird netting (or "fruit netting" as it is called here) to cover them inside as sort of barrier. It was fine plastic netting with openings about 1/2 - 3/4 inch wide. But one of the button quail got caught in there one day and tangled up, and died! I also was able to rescue a finch who got tangled up.
Then we tried "sports netting" which was made of twisted nylon with larger opening, much like a tennis net. (It was expensive!

) Again, one day when we were on vacation the bird sitter found a quail completely tangled up in the morning, dead of course. A few weeks after that I rescued a young budgie who somehow got himself tangled up in there. And that was IT! No more netting.
We build frames with perches made of thin wooden sticks to obscure the open windows. They are about a foot or so apart, and enough to make the birds aware of an obstacle. And they actually LOVE it. They sit on these perches all the time. The only downside is: I have to constantly clean the windows now because they get all messy.

But my birds are happy and the main thing is, it's safe.
No more netting for me!
Sorry, that became quite a lengthy answer but after actually losing birds to the netting I am pretty passionate about the topic...
