Why my finches are throwing eggs?

[monjur sayad]

HI, I have some parakeets in my room with 6 pair of finches. Both are in different cages. If I place finches and parakeet in different cages on same place does finch will do breed?? Because my finches throw eggs and don't laying on eggs and also some of them don't interest in nesting. Some people says I place parakeet with finches thats why they are doing this. Thanks

If they are not in the same cage it should not be the reason. Some reasons are:
Finches not all the way into breeding condition
Too young
Wrong time of year
Not enough protein or missing some vitamin
Male might be throwing eggs (remove male)
They will also stop nesting during and after molt.
