I think if the nest box was too small, that could prevent them from laying, otherwise I find mine will pretty much explore anything I place in the aviary. Even if they are aviary or wild bred birds, these guys seem to have a very inquisitive nature.
When I was a kid, my parents traveled around Aust alot. One place that sticks out in my mind was out in the whoop whoop, a flock of wild rainbow lories used to visit the camping grounds we were staying at. Every morning and night, the birds would visit for a free feed. I managed to talk mum into giving me a piece of bread with watered down honey on it. I raced out to feed the pretty birds. They flocked on and around me, pretty cool when you are a 7 yo old. lol
I think over time and persistence, you do have a chance at quietening them down, maybe just not as quiet as a handraised bird.
Oh, lories will not usually breed if more than one pair to an aviary/cage.
I had all mine in a large aviary and not one bred. After having them DNA'd, separated them, they started breeding.
A big breeder of lories said they will not breed when housed together, and that rang true with mine. Not sure if having them in separated cages but as neighbours also affects them as they may still think they are together. I have mine in separate cages but away from each other now and have had success with breeding.
