I know it can be exciting to breed but you'll have to be patient

. If your ringnecks are young, chances are it will take them a while to get it "right." One pair that i had almost took three years before all eggs were fertile. The female would work the nest, mate, and the pair would feed each other. This went on for three years but I got no babies.
Also, the birds you are breeding, were they hand fed? If they are, you could expect more time for them to successfully reproduce. Do you know how old your ringnecks are?
The only thing you should do now is just give them a proper diet, privacy, and lots of time and love

. I promise, the wait will be worth it. Besides, this extra time will allow you to get to know your birds.
Hang in there buddy
