cockatiel parents and babies

Question
My cockatiels started breeding again when their babies were only 5 weeks old. Two new babies just hatched 2 days ago and the mama has nothing to do with them. As of tonight now the dad is not taking care of them. They eggs were laid on the cage floor just like the previous babies. I don't want these babies to die and I don't know how many hours they can go without heat from the parents or food. HELP!!!!

Answer
hi. thanks for your question.
unfortunately this is a common occurrence and is why many people breeding birds choose to remove the eggs and/or babies from the cage and care for them themselves. additionally, some choose to remove the male from the cage immediately after breeding to prevent such an occurrence. the bottom line is that any time you have a breeding pair, you need to realize that there is a possibility of the parents not properly caring for the babies and that you need to intervene.
i realize that it is too late to figure out what went wrong and you have a crisis situation at hand.  however, you are going to have to intervene immediately and care for them yourself.  they cannot go at all without heat or food from the parents and this is a situation that requires immediate attention. many owners with breeding pairs have to intervene as bird parents often abandon, neglect, or abuse their young. that is why you always have to be prepared to step in when they are not up to their parenting duties. it is your responsibility as a bird owner to take over.  if the parents are not caring for them now, they most likely will not.
take the chicks out of the cage now as well as any unhatched eggs. the unhatched eggs most likely will not hatch if they have been neglected so you will need to focus on simply saving the babies that are still alive. you will have to keep them warm and fed since their parents will not.
the care and handraising of baby chicks for beginners is very long and involved so i am going to give you excerpts from articles as you will now have the responsibility of keeping them warm (brooding) and handfeeding them until they are able to feed themselves and able to keep themselves warm (until they are feathered/fledged). i am warning you ahead of time that this is a very involved and time consuming process. you will need to be aware of the risks involved as well as the time involved in trying to save these chicks lives. as such, i suggest you also consult with a local breeder/animal shelter/avian vet if you are unable to do so or need more help. you can also research more info online once your chicks are warmed and stabilized. on a cautious note, consider this in the future when you place a male and female 'tiel together:
this article is very detailed and in depth about how to make your own brooder/warmer and about warming the babies yourself:

information on handfeeding them yourself is here:

PLEASE DO NOT DELAY IN THE REMOVAL OF THE CHICKS FROM THE NEST AND IMMEDIATELY BEGIN WARMING AND FEEDING THEM. THEY WILL DIE WITHOUT YOUR INTERVENTION.  
good luck and i hope this helps. alicia
