I have 3 female love birds and 2 male lovebirds, the females killed one of the males, what do you think?

It's not as uncommon as you might think for lovebirds. The name doesn't really suit them as they aren't really all that loving. Lovebirds are quite territorial, possessive and can be bullies.

Separate the lovebirds from the finches, and take away 2 of the females into a separate cage.

Lovebirds can be very nasty.remove the finches or lovebirds as soon as possible into another aviary.Do not try adding another male lovebird to even things up or there will be some more fighting and deaths.

When you add new lovebirds to others,you put them all into a new environment and even then there can be fights.How they got the name lovebirds we will never know.

Theyre feminists plotting an aviary take over. Even the odds and get rid of one of the female lovebirds

Lovebirds are very aggressive animals and should not be kept with other birds, ever. They will bite, even bite off limbs, or kill. females, so ive heard, are especially mean to other lovebirds. Separate by gender and species. Actually, I think one female for one male, or just by themselves.

I'm not really a bird expert, but maybe you should think of acquiring separate cages for the birds that show hostility. Also do a little research into whether or not its safe to house those two species of birds together.

Im not an expert but I have been told that if you have lovebirds you should only have 2 (1male 1 female).

separate them!

I think she didn't like him.

I think that you should separate them... and your question just made me laugh... thanks XD.
