Even if they are male and female they WILL FIGHT EACHOTHER!!
They need time to settle in!! Introducing a nest box 2 day
sfater purchasing them, are you plan on killing them or having
babies? If Babies, do your research and let them settle in. If
they were just imported to whatever countyr your in, they will
be VERY stressed, upset, and angry. You will probably want to
get another cage to seperate them in but have them right next
to eachother about 1 foot apart, wait untill next season...
and make sure you read EVERYTHING about toos first!! So I wont
have to right a whole story on it :)
