What happens when male and female parakeets mate?

They need a nesting box on the side of the cage where they have privacy. If conditions aren't "just right", parakeets do not seem to breed in captivitiy. You may need to contact a professional or possibly even consult with a book on the subject. ----------- I've never had a problem breeding parakeets in captivity! You have not properly set the birds up for breeding OR they may not like each other! If they mutually groom each other and play together, then that is probably not the problem. To properly set up a pair of parakeets for breeding, you need two healthy birds and you need to be certain you have a male and female. They breed mostly in spring or early summer. The longer daylight hours and presence of lots of fresh foods (fruits, veggies, greeny leafy foods, bird-safe people foods) indicate to them that there will be sufficient food to feed their young. They also need a stable routine, being provided food and water at the same time every day, and a bit of privacy. Once they have been properly set up, introduce the nest box. The male will, after checking it out for a day or a few days, go inside and, if he approves, come out and let her go in. After that, they will mate. Visit Eliteparrotsclub.com for more information!
