Hens will push other turjeys away from their nests. Seen it first hand if a hen that was strolling by feeding went into the think brush for 15 to 20 minutes came feeding out as a flock starting cruising by she got pretty vocal at the flock which put them on alert but was lucky enough that I got my mentee on the tom trailing. Most hens that are laying or nesting break of from the flock and are alone. Tom's do not care they are looking for more love. That is why you will starting see them in bachelor groups starting about now. They will feed in a flock after fly down but around mid morning the hens will separate from the flock and hed to lay eggs. Oh and hens once they start nesting or incubating her eggs she does not roost she stays with that nest and if she does roost it is very close to her nest. So yeah being close to that nest really shouldn't help in hetting toms. Also studies have found that if you bust a hen off of her nest a lot of time she will abadon that nest. Take in account most of these studies were done is the SE part of the country.
