LNCAG, what state are you in if you don't mind. I am sure you have told us, but I need a refresher!
I have an outdoor bird (screened) room on part of my deck, it has an enclosed roof, so sadly no sunshine comes in. Out of my 3 it is my Amazon that LOVES it out there, my 2 greys wont have any part of it unless I go out in it and they stay on my shoulder for a bit...quickly wanting to go back inside if I DARE to try & leave then there. It is attached to my living room where there is a window I can open so its easy to go back in when they desire..which for my Amazon rarely..but my greys are NOW!!
