Hormonal changes: Estrogen and progesterone are two hormones that play a role in egg-laying. Increased levels of these hormones can trigger ovulation and the release of eggs.
Environmental factors: Long days and warm temperatures can also stimulate egg-laying. Providing your parakeet with a nesting box or other suitable nesting material can also encourage egg-laying.
Nutritional factors: A diet rich in calcium and vitamin D is essential for healthy egg production. Make sure your parakeet is getting a balanced diet that includes plenty of fresh vegetables, fruits, and seeds.
If you are concerned about your parakeet's egg-laying, it is always best to consult with an avian veterinarian. They can help you determine the cause of the egg-laying and recommend ways to manage it.
