Will a Zebra Finch Sit on Another Zebra Finch's Eggs?

I have three zebra finch pairs in three different separate cages. One pair has been my best breeding pair, it's their 2nd clutch this year. They had five healthy chicks 3 months ago and now they have again laid 4 eggs. My question is, my 2nd pair had mated, but it's hen was not laying eggs, so I tried to exchange the cage of my 2nd and 3rd pair. I mean I simply put my 2nd pair into a new cage and the 3rd pair into the 2nd cage. Then I saw 3 eggs in my 2nd cage, which my 2nd pair had laid. What I did next is I reversed the situation back to like it was before. I did undo my exchange, but this time the zebra hen didn't go into her nest.

I then took out its 3 eggs and then put it into my first cage in which there are already 4 eggs and their parents are sitting on their eggs, now after having put 3 more eggs in their nest, they are now sitting them, like all of them. I mean, has this female finch accepted the 3 new eggs, and will they hatch these eggs too? Since I know that after 3 to 4 days their old eggs will start hatching.

I am anxious to know about their behaviour. Do zebra finches hatch another's finch eggs? Or will she know that these eggs are not hers?
Your kind response would be highly appreciated.
