Ask anyone about lovebirds, and I guarantee they will assume that to be happy and healthy, these beautiful creatures must be kept as a pair.
This is not strictly true. What is true is that a pair of lovebirds who have already bonded shouldn't be split up, however if a lovebird has been raised by hand since he was a baby then they can make excellent familty pets on their own.
Lovebirds do require some handling and care on a daily basis - if you neglect them for more than a couple of days they can actually become quite surly.
Quite a small bird, many folk make the mistake of buying a smallish budgie type cage to house them in, however this is not really the best way to go.
