Welcome to the forum and I am so sorry you are having this problem although I am sure that the parent birds are even more devastated than you are! It would be impossible for anybody to actually pinpoint what the problem is without actually being there and observing your husbandry and the parents. Now, I hope you don't take this the wrong way but it is obvious that you are doing something wrong because we, humans, completely control pet birds environments and their breeding triggers so whenever a bird is not breeding right, 99.9999% of the time, it's our fault (I don't breed parrots because I don't believe they belong in captivity but I have bred purebred song canaries for many years). For one thing, macaws would not be breeding in the wild right before spring starts (I was born and rasied in the Southern Hemisphere so I know how the seasons go there). This tells me that you are not keeping them at a strict solar schedule which is essential for captive birds wellbeing even the ones we don't breed. Breeding off season depletes the parents and makes for weak babies. I don't know if this is the only reason or if this is compounded by other problems (location of cage and of nest, diet, type of artificial light, humidity, temperature, etc). You need to learn a lot more before you breed them and then review your entire husbandry.
In the meantime, you will need to take the nest out of the cage and allow their endocrine system to go back on track with the seasons correctly and rebuild their reserves because insisting on breeding when it's not working out ends up killing or damaging the parents for life. And this takes two whole years so the sooner you start, the better off the birds will be.
