I might get a new bird!!!!

If you really want to have a bird that is more tame, you may want to have one new budgie and keep it in its own cage so that you can bond with it before allowing it to bond with the other birds. In that case, you would have the new bird out of the cage at different times from the existing birds.

If you are considering one or two more birds the first thing to consider is where you will put a second cage. Since your two birds are established in their cage they probably will not take kindly to having one or two newcomers moved in with them. Also, if you are considering a bird of another species it probably will never work to have them caged together.

If you get two more budgies and have them in a separate cage during the quarantine period (most recommend four weeks), you can then introduce them on "neutral ground"--outside of the cages. If they get along, they may all start spending time in one cage, and you may then be able to dispense with the second cage.

So, the first thing to decide is whether you want one separate budgie that will be bonded primarily with you or whether you want to have four birds in order to have the fun of watching them interact, but understanding that they will probably not be more tame than your current birds.

Since you currently have a male and a female budgie, if you are going to get two it would be best to get another male and female. In that case, look carefully at the information on determining gender. Many pet stores do not know how to determine gender, but think they do. They may say they do, but they can be wrong :-(. An imbalance in the number of each sex can lead to conflicts as the more numerous sex compete for the one bird of the opposite sex. On the other hand, if you keep the two new birds in a separate cage sex will not be as important.

Another pair is a fine idea, but if you plan on getting another kind of parrot, I strongly suggest getting a baby and hand raising it to live in a separate cage. There are very few instances of different species of birds doing well together in a caged environment. The risk of violence is too great. If you choose to get a tiel, the tiel may be picked on by the budgies because of its quiet nature. If you got a love bird, the love bird would definitely beat up your budgies. Think about whether you can afford the money and space for a new cage set up, and whether you want to take the time to work in two cages every day before you decide.

The more birds you have the greater chance for less bonding. If you want to breed them be sure you know what you are doing as this is a life we are talking about.
