Zebra finches abandoning their babies

[AGG]

I got an aviary and a couple of more birds for the purpose of breeding them. Its taken me 1 year for them to actually start breeding and laying. I have 2 zebra finche pairs. One has laid 5 eggs while the other pair have 3 babies hatched in their nest. This whole day ive been coming outside to check them. Everytime ive checked they've either been out of their nests or sitting in other nests that are usually never used. I took out all non used nests so the finches would go into their own, but they aren't. I checked just before to find both pairs sleeping outisde of their nests leaving the babies on their own in the cold. Feel like restarting my aviary with different species because zebras and diamond doves just done work for me.
