I have out this in the newby section but as its about birds i will post it here also

I will start by introducing myself, or us.
My name is Wayne and the more sensibly half is Tracey, by that i mean she agrees i need something to slow me down a little and is up for it as to going off roading and building off roaders.
I have just sold up and gave up messing with cars etc and have decided to start keeping birds, i have had budgies and cockatiles in the past and i have decided to do it again but on a better scale with an aviary, so as i have spare room where the worshop is i will be building an aviary to house cockatiels and maybe some ringnecks, we will see about the ringnecks as i sort out the setup of the aviary.
I have a space of around 18`x 9` to use and wil be having a bird room with inner flight and main flight, the inner will be around 9`x4.5` and the flight will be an L shape of 9`x 6 , 4.5`x 6`, should be good room for a few cockatiels and maybe a pair of ringnecks, i would like to keep them together but there has been so many differences in opinion about keeping parakeets and tiels together i am not sure yet, it maybe wise to keep them in the ringnecksin there own flight, we will see.

Anyway i will keep you updated to the progress of the build and how things are doing and if you will i will be needing a bit of advice along the way i should think, a bit different from keeping birds in cages.

First question though, how many tiels would be ok for the flight of the above size.
