Bikbok claimed Archie's inner chamber his cage, and then spent the afternoon building a sort of nest and singing lots, I think trying to attract a female. He defended it so fiercely too lol. Poor Archie wasn't allowed in, so after extracting the bird, we put a box with hay in Bikbok's own cage, can't have him claiming the wrong territory. Archie just watched from afar, he doesn't really go in his house during the day, he prefers the cardboard box and the coconut mat.
