Health & WellbeingI have two happy male society finches in a cage approx 3 feet long and 14" wide, 24.5 inches high. Can I add a 3rd male. There's one that has been in the pet store for months. Awful. Tiny cage.
Ideally, the more space the better, and three birds should have a flight cage that is big enough for them to fly back and forth horizontally in (finches tend to like horizontal rather than vertical cages). You also want to make sure each bird has their own access to food, water, and bedding areas, with dividers such as perches or toys to break up the space and prevent fighting over territory. If you do introduce a new bird, make sure to keep him separated for a week first to prevent the spread of any illness, and to make sure he is healthy enough to be added to the flock before doing so.
