Female lovebirds lay eggs in a nest created from leaves and twigs, or a nesting box provided for caged birds. A lovebird shows signs she is about to lay eggs by preparing her nest for the eggs. A caged bird with no access to a nest makes use of any available container, such as a feeding cup.
Lovebirds reach maturity between six months to a year and are then ready to mate. Lovebirds begin to lay eggs five to 12 days after mating, usually one egg every other day. The size of the clutch is generally between three to seven eggs. Incubation time is about 23 days for each egg.
Female lovebirds also lay eggs when there is no access to a male lovebird, although these are not fertile eggs. Separation from other birds curbs excess egg laying. In addition, placing the cage in a dark room imitates the short days of winter, when mating does not occur.
Egg-binding is a common difficulty among lovebirds, which can be fatal if not addressed when signs of distress are shown. Egg-binding occurs when the lovebird is unable to expel the egg. Veterinary intervention is necessary to prevent a fatal outcome. Treatment of egg-binding includes medication, needle aspiration or surgery.
