Red cheeked cordon and gouldians

[paul1966]

just a question, I just moved my birds around,I had gouldians and a pair cordons.the problem is the gouldians, keep trying to settle in the nest. I don't wish to breed gouldians, I have enough.very nosey gouldians. So now the cordons are back in a cage, two meters by two,by two meters. Can I add another pair of cordons in that size cage,or better choose another species, advice... I had cordons in cage before and lost two clutches of young, that's when I added the gouldians. But like I say they kept going into cordons nest.

Multiple pairs of Cordons will fight.

Unless they are set up as all young birds & in bigger aviaries. Established pairs where at least one has an existing territory will result in persistent aggression.
