Does anyone here have them? What are they like? I might be getting some in a while, so I'm trying to find out all I can about them. My cage is 39x21x32 inches. How many birds could fit into it? Is it possible to have a canary and pair of zebra finches in the same cage? How "tame" do they get? I've heard that they don't get tame, however, it seems like eventually they must get somewhat used to humans. Is that so? I don't have any more actual questions (at the moment) but would appreciate it if someone could simply explain what its like to have zebra finches as pets...
