The only chance one budgie would be able to kil another is a
nest box with two bird and small cage= death. Make sure the cage
is BIG. I have 9 budgies and I never had ANY deaths, even when
they're all in the same big cage I have for them. Now two
budgies in a tiny cage will be stressed because of the cage size
and need a bigger one. The death wouldnt of happened if the othe
rbird was able to get away from the attacker 9thats why they
need bigger cages, I do not know why people think small cages
are good for small bird, IDIOTS)
Even if the birds are male and female, a small cage = disaster.
And a small cage with nest box equals torture and disaster...
