Any experienced advice please. My turkey mama was sitting on eight eggs. She hatched four and left the nest with the living chicks, because the chicks couldn't get back into the nest. I put up a ladder walk-up board for the chicks, but the they aren't using it. I'm pretty sure the four unhatched eggs are fertile because we have two toms and three hens. My hen has been off the nest the whole day (today is the 17th of June) and I estimated the eggs to hatch around the 18th of June. Is there some way save the unhatched so that they will hatch?
