broody bantam with ducklings and potentially quail eggs

[crowningbliss]

i have a bantam with 4 ducklings just hatched 2 days ago. she had just been broody a couple of weeks when i gave them to her, because they were starting to hatch, and the leghorn who'd been sitting on them all month seemed to be rejecting them. the bantam is doing great with the ducklings, just sitting still with them. now i have some fertile quail eggs, and i wonder if i can give my bantam these quail eggs even though she's got 4 newly hatched ducklings? i understand quail eggs only take 13 days to hatch. could the bantam sit on them with ducklings to care for, and could the quail babies and ducklings get along as one family?
