Chris -
I had rehabbed around 350-ish birds, before I got to the point where I could train one up in four days... (My biggest problem child was a ruby macaw, and it took me 8 months to get her behaviors under control! So, it very much depends on the bird, and what they've been through, and finding what they respond to, and also having them respond to it... ) My Sally took four months to fully train. By the time I got Maggie it was just second nature. And, yeah, I also taught bird handling classes... so I wasn't exactly a novice at that point. I knew what to do, how to do it, and she just responded... part of it is that she had a naturally sweet temperment, she just hadn't been handled in 8 years, and craved love and attention. She didn't forget how... she was just nervous of it at first.
And I had a birdroom with all the stuff in it...
And an entire flock from which that bird could watch the interaction and decide she really wanted that...
With mine, my first conure was raised out on a playstand, so from the get go, I had a free range parrot.
It was probably along the lines of 2-ish years before the rest of them became free range parrots. And that stuff started because I figured out Sally had not only been letting herself out after I left for work in the morning, but she would lock herself back in before I came home...
So, yeah, if she's doing that?! Uuummm... why do I bother to lock the cage doors anyway?!
It was kind of a no brainer for me.
But you've seen my playstands... THEY WANDER OUT OF THEIR CAGE, AND ONTO THOSE. THEY HAVE WAYS TO ENTERTAIN THEMSELVES ALL DAY LONG IN THEIR OWN ROOM. And they don't wander around the house getting in trouble. And NEVER HAVE. They go to "their spots."
So that's why I do it, and why I can.
Boniface:
Mine don't care for being caged up either. The only one who really fusses about it are the macaws. I don't think any living thing likes to feel trapped... though some neurotic birds associate the closed doors with "they can't get me in here. At least I'm safe."
Maggle did 8 years in solitary, and doesn't like to voluntarily go into her cage. She starts "the pathetic act" the minute you close the door.
I only put them in for cleaning purposes anymore, unless I am going out of town, and someone is coming in to feed and water them.
