My three zebra finches are in a dedicated relationship, 2 females 1 male. I tried to introduce a second male and he got beat up pretty bad. Which means they can’t be housed with any other birds or be separated. I caught a resentment against these 3 for I was the one to have to take care of the second male after he was attacked. But these three do make great pets. There very small easy to clean up after don’t eat to much. There going to need a large cage anything else would be inhumane.
