I am not completely sure how old she is but I know she is under a year old. She has been sitting for about... eh maybe 4-5 days. There aren't a lot of distractions she has been sitting practically nonstop. Sometimes I have to force her off the nest to stretch her legs. When she does get up though another one of my hens just comes and takes her place. They are all the same age, I have two other hens and a Tom. I tend to check on her everyday, she doesn't mind me coming near and I often give her a handful of feed and I offer her water. I have my incubator already up and ready just in case
I would not force her off the nest, IMHO that will just tend to dissuade her from sitting. I would also block the other turkeys off her nest, I learned that one the hard way no good will come of it. It will get her to stop and can lead to extra eggs. Which you do not want. I never look under my hens when they set.
