I tried letting two Midget Whites set on a nest and when the eggs started hatching they started fighting and killed most of the new poults. I believe their motherly instincts kicked in and they were trying to protect the young from each other. However, other people have had success with more than one turkey setting a nest. Personally, I would move two hens, put some of the eggs in an incubator and let one hen have the nest with about 14 eggs.
