I have a 5 year old Umbrella Cockatoo. I am desperately trying to find an economical way to build an outdoor aviary for my baby. The dimensions are 15-20 feet long 8 feet tall and 4-5 feet wide. The expense of buying stainless wire is out of the question. I have access to powder coating whatever wire I get if that is what is safest for her. Should I get chain link or another type of wire? Please be specific with your suggestions. I have researched and hunted and the more I look on the internet the more confused I get. She will spend alot of daylight time in it, therefore, I know she will climb and chew of it. PLEASE HELP?
