Turkey nest

I was practicing my turkey calling, and observed some turkeys moving about in my back yard. I was following this hen with my binoculars as she moved through the yard and woods. She walked up to this birch tree and stopped. There was another turkey sitting on the ground. Now I have watched this turkey for the past 10 days, while playing with my dogs, mowing the lawn, filling the bird feeders, and she stays on her nest. She moves around a bit when she thinks nobody is watching and there are no other noises. See the pics I have attached.
