3 love birds conflict?

just got them yesterday, they were adjectives getting along once i got them (the owner said she had them for 10 months without a problem) and the subsequent day i see 2 of the lovebirds together and one side, and the isolated one is by himself on the other side. why is happening and why didnt own before?

another question: i think its breeding season for these 2 lovebirds and whether i leave the other one in another cage, will i know how to put him back with the 2 other birds once breeding season is finished?
WHY DON"T I LOVE MY OTHER BIRDS?...
Answers:    love birds. google it will tell you they will pick a mate for time. three..take one back.
that would be the best bet. the sales entity should have told you.
