I just had a look at your post history, and I have to say it is very disturbing.
I see that you had previously asked for breeding advice, and were told to NOT breed your birds, since you have no idea what you are doing. This would have been good advice to follow.
I also see that your birds have had health issues:
Your budgies are having issues breathing and have nasal discharge. Did you take them to a vet as told?
You've had issues with a sick cockatiel. Did that get looked after?
You have French moult in your budgies. Did you take them to a vet to confirm and get treatment?
Zinc poisoning.
One of your lovebirds just died. Do you know why?
You are trying to also hand feed a baby cockatiel, but it was being attacked by ants, because it was being kept in a cardboard box. Have you resolved this issue?
Over all, these are ALL major alarm bells. What frightens me the most is that NONE of these threads have updates on the condition of the birds involved. Have any of them had vet care as recommended??
Please, for the love of god and for the safety of your birds, STOP trying to breed until you have all these health concerns under control and after you've done plenty more research on how to take care of them.
