baby parakeeet- male was feeding and died

Question
We had a pair of parakeets the mother laid 3 eggs.  apparently only one was fertile and it has hatched 3 days ago.  Originally the male bird was not allowed into the nesting box but as the time of hatch neared the female warmed up to the male and let him feed her.  eventually afte the bird hatched she would actally let him in the nesting box.  He looked somewhat emaciated, and had lots of excrement but was continuing to feed the mother and I think the hatchling.  Yeaterday afternoon we found him dead in the nesting box with the baby under his wings.  The mother was not paying attention to the baby.  With gloves we removed the male and closed the nesting box and went to get food and a dropper, and warming light at the pet store.  By the time we returned the female had resumed feeding the baby.  But now she is looking tired.  It is my understanding not to intervene and let mom do her thing.  But this morning she was on her perch and looked a little weak.  We do not want to lose her too. Any guidelines for when of if we should take over the feeding process?  any help you can provide is greatly appreciated.  

Answer
Hello, I am sorry to hear you've lost the male. But it sounds like he was sick o take the baby and handfed it right away dont wait any longer. Take the mother to a vet right away waiting a 'few days' could cost her her life. Clean the cage remove the nesting box and let the vet tell you the rest. I wish you luck in your handfeeding, I've rasied two budgies right from day one before both lived to be happy helthy birds so it is very possible for the bird to be fine if you handfeed it properly, grab a handfeeding book fro your locale petshop it'll be of much help.
