One of the locally owned bird stores around here has a display cage with a cockatiel and a parakeet in a cage together. I'm just curious on if this is a good idea or not. I'm kinda thinking of doing this myself if you guys say its a good idea, as I have both a cockatiel and a parakeet (seperate right now). Is it stressful for either of the birds? I know they both share the same native area, so I'm sure they'd come in contact in the wild and these two seem to love each other when i have them out on the playpen together.
