I'm thinking this too, I think I took what he said about the bird "proving he was fine out in cold temperatures" the wrong way, and that the bird will only be outside when the temperature is appropriate....Just because a parrot could possibly survive in below-freezing temperatures does not at all mean that they should, especially when the species of parrot comes naturally from Australia. That's what you have to look at, what is the normal temperature range in the environment where they originate from and live normally in the wild.
okay, let me clear everything up so we can move on. I live in the Northeast of Massachusetts near Nashua New Hampshire, of course I wouldn't have my birds outside in the winter or any day that seemed questionable. I know she tolerates low temperatures because her past owners would often run out of heating oil. Last winter, I was living with them, and they heated the house with the fireplace until the middle of December. Chicken lived in a 3 season porch with plastic over the single pane windows. I think it was December before I found out that there was a 12 inch square glass piece missing from the exterior door allowing a draft behind the blinds. That room was definitely in the low forties overnight, Plus the draft, and they never showed signs of being cold at all, and by they I mean chicken the sulphur-crested and blueberry her friend parakeet.
So anyways, chicken spends the day on the outside of her cage as it is, she just hangs out and talks to birds out the window or whatever it is birds do when I'm at work. She could easily destroy all the things I have in storage in the room she's in, but believe it or not I trust her not to as long as it's Out Of Reach of her cage.
**FYI she will absolutely climb and walk around the house to get to me when I'm home if I leave the door open, but she won't walk or fly to destroy something in the room. **
**And Fun fact, blueberry lives in chicken's cage and fits Between the Bars. He stays in and on top of the cage for the most part as well, sometimes he likes to fly laps around the room, and on occasion he'll explore the whole house. It was only when I took him home that I gave him his own perch near the top of the cage that he only goes to sleep on.**
I figured if I made a big outdoor enclosure that was safe enough, I could bring chicken out there instead of cooping her up in her cage which she's not used to, or keep risking her being free on a daily basis . I just want to give her more space and air because she's a bird and she deserves it.
Like I said though, if it's not possible to make it that safe, I'm building an adjacent Greenhouse so that we can hang out together anyways, going to plant some flowers and stuff and put a bench in there, and a small door so she can come over and chill.
