Cockatiels will breed any time of year, but they need a decent amount of light in order to breed. Make sure that your cockatiels have a source of natural or bright artificial light for 10-12 hours per day. Before breeding, it is important to ensure that your birds are eating well. Feed them a balanced diet of food that is meant for cockatiels. Check on your birds often to make sure that both cockatiels have equal access to food and water dishes. If one bird is guarding the food and water, then you can add extra dishes of food and water. Good foods to give your cockatiels include: cockatiel seed mix soft foods such as greens, pasta, cooked rice, cooked beans, moist wheat bread sprouted seeds cuttlebone or mineral blocks for calcium supplements (to sprinkle over other foods) such as spirulina, Echinacea, and Prozyme fresh, clean water (change it a couple of times per day) Your cockatiels will need plenty of room for breeding and even more space after their young have hatched. Make sure that the cage that you put your cockatiel pair into is 6 feet by 3 feet by 3 feet. You can place the pair into their enclosure a few weeks before you provide a nest box so they can get to know each other and to get into sync for breeding. Place the cage in a quiet part of your home to give the couple the privacy and quiet they will need to breed, brood, hatch and raise their young. After the pair has been together for at least two weeks and they are getting along well, then you will then need to provide them with a nest box. As you choose a nest box, some things to consider include: Material. There are many types of nest boxes available including metal, plastic and wooden ones. Wood is a good choice because cockatiels will chew on the entrance to customize it to their specifications. Size. A one foot by one foot box is sufficient for breeding cockatiels. Rear access door. Some nesting boxes come with a rear access door so that you can check on the chicks without disturbing the hen. Bedding. Cockatiel parents will use bedding to make a cozy and safe nest for the chicks. The best materials for nesting are low dust pine shavings or uncolored paper materials like newspaper or plain white paper towels. Do not use cedar shavings because the oils in this material can kill or injure the chicks.
Provide 10-12 hours of natural or bright artificial light per day. Feed your birds well. Put your breeding pair into a large cage together. Create a nest box.
