When does a love bird lay eggs?

At about age 1 to 2 lovebirds start to lay eggs. You need to buy a nesting box (lovebird appropriate) in condition for your lovebirds to lay eggs. you can get a nesting box from your local pet store. but make sure you fill it with soft stuff or the egg might brake. If your female lovebird lays an egg it will not be fertile unless she has a mate.
