Suggestions needed for broody hens and chicks

We made a mistake... We have 3 broody hens, and they started in succession, second hen starting a few days after first, and third about a week later. Somehow 2 of the first hens eggs got mixed into the second hen's nest. So now the first hens eggs are hatching, including the errant eggs in Second's nest. Is Second going to give up on her eggs to care for her 2 hatched chicks? Should I add Seconds unhatched eggs (if she abandons them) to Thirds nest, and when they hatch, try to decide what to do with Third's eggs if she abandons? Is it advisable to steal the chicks from Second and give them back to First in hopes that Second will stay for the duration of her own eggs? We do not have an incubator. Ahhh I hope that wasn't as confusing as it sounds.
