How often do you clean the cage?         
     We generally change newspaper for paired finches every other day, while hosing
     out aviaries daily.

     How often should I change the water?
     Fresh water can't be overdone.  I recommend fresh water daily for all birds.

     If I want to keep 2-4 finches what is the minimum cage size?
     Gouldians like length rather than height.  So I would recommend at least 36" L x
     18" W x 18" H.  If you have the room a longer cage would be even better.  They
     like the length for flying.
     
     Can I keep other birds with my Gouldians?
     Yes you can.  Though not any bird.  They are best kept with small to medium sized  
     Finches such as Zebras, Cordon Blues, Societies, and my favorite Owls.

     How long do Gouldians live?
     A lot will depend on you and your care for them.  If you feed a good diet and     
     keep them  healthy at least 8-10 years.
