Well, it's not quite a dog's life... well, it's not at all a dog's life. This peahen lives in a cage of about 27 cubic metres - which isn't as large as you may imagine it to be.
I understand that sometimes it's for their own good that some birds are kept in cages, but generally I'm not much into keeping a bird locked in a cage. I don't think I'd ever be able to keep a bird as a pet... unless of course it was an ostrich and I had a farm. ;)
