They may or may not show up. Depends on several factors, food sources being the most immediate need, as between now and green up food is fairly limited. If you have food, and the hens stay they may show up.
Second thing to think about, is nesting cover, if where you hunt has little nesting cover then the hens will leave for areas which fit this need.
One other thing which can play a huge role in where they end up when the season opens, is that here in a few weeks the gobblers will really start hammering every morning. The hens will go to them, if those gobblers have staked out areas with plenty of food and good nesting cover then they will stay there, if not they will come back to where you have been seeing them.
My personal feeling is that with hens that you see all the time, that there are gobblers there all the time as well. You just may or may not see them as much. In a few weeks on a nice morning, go listen. If you hear nothing, then it might be time to get worried.
