I am the proud owner of a single parakeet. I want him to have a larger cage so he can stretch his wings a bit, and maybe eventually get him a friend. I am not exactly experienced, so I am hoping that someone would be nice enough to help me on this-- First: What CHEAP material do you recommend for a cage? I was thinking part plexiglass (with LOTS and LOTS of holes drilled in it so he can climb/breathe and so that I can attach perches easily) and part untreated wood? I also have a metal grille that came with his old cage that I would use for the door. I don't want it to be much taller than two feet, because then he'll waste the bottom part of his aviary, but I do want to be pretty wide/long. Does anyone have any pictures of their DIY aviaries or recommendations they could share? I want him to be happy, and yet don't want to spend more than $50. Thank you all so much! I really appreciate it!
