My parakeets are fighting

Question
QUESTION: I have 3 parakeets, 2 females and a male.  Tweety is the oldest, and Bindi and Sui are the same age.  Recently, in the past few days, Tweety has become very aggressive.  She is fighting with Sui, and even hurt Sui's foot today.  Tweety has been laying eggs for about a year now, and I make sure she has a mineral block, water, food, and a cuttle bone to replenish and vitamins she may lose during this process.  But, now she is not allowing anyone else to eat, she keeps fighting and bickering with the other 2 birds, and I don't know what to do.  They even are starting to bite us very hard, and Tweety is the only one that is finger tamed...and she doesn't even want to come out of the cage.  She used to come and give us kisses, and she doesn't even do that anymore.  PLEASE HELP!

ANSWER: Females tend to be more aggressive than males.  This is especially true if they're raising eggs.  I would try a trial separation.  Find another cage, and put Bindi and Sui (cute names by the way, I miss you Steve Irwin!) in it, away from the aggressor. After a few weeks or so, try putting them back together again.  This sort of out of character behavior is usually temporary.

Keep me posted, and let me know if you have any other questions!

QUESTION: We are in the process of moving from Nevada to Alabama and it's going to be about 4 weeks before we can seperate them. We were planning on it though...even getting them each their own cage. Or getting 2 cages, and letting Bindi (the boy) go back and forth between the 2 cages.  Until we get moved...do we just suck it up and deal with it?  I just don't want them to hurt each other or kill each other.

Answer
One thing you can try in the mean time is get a spray bottle (you can buy these for about a dollar), set it to the stream setting, and spray Tweety with water if she gets aggressive with the others.  Its something that won't hurt her, but it might distract of startle her into stopping, at least temporarily.  I can't guarantee it will work, but its worth a shot.

Its highly unlikely that they will kill each other, or cause any serious harm.  But of course, you don't want to see them get hurt!  They will probably go back to a peaceful coexistence; I had a female that was pecking her mate's feet until they bled, and eventually she stopped, and they've had five babies since then!  So don't give up hope!
