hens being broody

[BuffMomma]

I have a question I have a hen that i thought was starting to sit on her eggs but she is not sitting yet she has a nest she rolls her eggs around the pen in the morning and puts them back into a nice nest at night and covers them with dirt she only has about 6 eggs right now been doing this for a about 8 days is she getting ready or what I have never had one do this some people say they will lay quite a few eggs before setting but others say she is just playing with them
