Zebra finch eggs and parents issue?

i have four zebra finch (two males and two females)..i have two nest box in the cage (one at the right of the cage and one at the left)...the birds have been laying eggs in each nest box....one pair per box...the box to the left had 4 eggs and the nest to the right hand 6 eggs...after about 10 days into incubation the birds in the left of the cage stopped sitting on their eggs...so i placed those fertilized eggs into the nest to the right...when i did that we move the cage b/c my parents wanted to rearange the the house....now the birds on the right stopped sitting on the eggs and now the birds from the left is sitting in the nest on the right and incubating all 10eggs....and the other two from the right are sitting in the left nest....will this be too much trouble for he parents to handle all that babies....they are sup. to hatch either tomorrow or the next day...it will be 16 days tm....
