For many birdwatchers, lovebirds make an ideal pet because of their beautiful colours and social behaviour. The name "lovebird" is derived from the bird's strong bond to other lovebirds, and the long periods during which paired lovebirds spend perched together. Despite their beauty and affection, they can be overwhelming with their excessive mating habits that lead to offspring. Moreover, more offspring leads to increased noise, smell and less space in the birds' cage. Fortunately, you can use several safe ways to get lovebirds to stop mating.
Remove all nesting materials and breeding boxes. Even though the female lovebird might still lay eggs on the cage's floor, they likely won't hatch.
Limit the amount of daylight hours. Don't allow the lovebirds more than 10 hours of sunlight per day. Cover nearby windows or cover their cage with a dark sheet to limit the amount of light they receive. Long days generally trigger mating conditions among lovebirds. Try to get the lovebirds as much sleep as possible.
Move the cage to a different area. It will take the lovebirds time to adjust to the new setting. Change the cage location every two weeks before the lovebirds adjust to the new setting and resume their mating habits.
Separate the males from the females. Place the male lovebirds in one cage and the females in another. Trade a male lovebird for a female lovebird if you're unable to keep a second one. Another viable strategy is also simple: keep only females.
Take your female lovebird to the vet. for hormonal therapy to prevent ovulation. The vaccine can be expensive, but it will act as a birth control option to prevent further mating.
