I’ve had my parakeets for two years, never saw them kiss even once . Saw them trying to mate once. The female has laid one egg but never hatched. This probably shows my parakeets have never bonded but what should I do
It sounds like this pair isn’t interested in each other as mates. They choose their own mate in the wild, and do not always like the mate we choose for them. After two years, you should see more interaction. If you really want to breed, then you would need to separate them and see about getting each bird another mate. There is still no guarantee you will end up with bonded pairs. This is one of many reasons why it is not easy to breed birds. All you can do is keep trying if this is what you want to do.
Thank you for asking Lafeber,
