Is the Vision M01 bird cage big enough for 3 parakeets?

you have not said if its the small, medium, or large but its not a matter of the size even if it did say i would stick with the two you have got if you put another one in what will you do if they start fighting to put 3 in a cadge it needs to be big enough to take the wing span of each bird then as ive said if they are not compatible they could fight especially if you have all females which you cannt tell there sex till they get to the age of the cere change when bought from young.

hope this helped you.
