This might help you out with planning for your aviary. Your best bet is to think big enough they can't eat it all and use some pavers or large rocks to keep them from bathing in the root zone of the plants. Good luck!

Thanks for the link!
Looking at yours, I need to add more hidey places! And sticks!
if a single bit of the broccoli is bigger than a flaxseed they leave it 

.I like the eggs though. So there aren't a ton of birds in this space and they don't typically stay for long.
