I have a 1 1/2 year old male canary. He doesn't sing much and am considering getting a second male that sings a lot. I am hoping they will stimulate each other to sing. I can get a flight cage, dimensions: Cage Height - Top to Bottom: 47 Cage Width - Side to Side: 36 Cage Depth - Front to Back: 22 They claim two - three canaries can be put in it. But does that mean only hens for the other canaries in it or would it be big enough for two males to safely be in it? I do have two separate cages that each are 24 wide, 20 long and 30 tall. But it would sure be nice to be able to cut down to only one cage.
