Hi, thats a great aviary and i think they will love the branches and shelves. I agree with Dayle and Barry though that it would be best to have a safety entry door, i have one and it is probably the most important part of the structure, without it i think i would have lost most of my Chips. Bailey and Asriel go straight over to the door when i come in the garden so there would be no way i could get in without them escaping, even if they are at the other end of the aviary by the time i would have opened the door they would be there, they are so quick.
