I am currently working on a project concerning the subject of life as a medieval serf; in particular, the manner in which they would have carried out their daily lives. Regarding the time range, anything between (roughly) 1000CE and 1381CE can be used. Any additional information regarding the manor or village they lived in itself would also be greatly appreciated. I understand that this is a rather broad question so any answer, regardless of its length, is welcome. Thank you.
I would look into the book "The Making of the Middle Ages" by R.W. Southern. He spends a large portion of the book explaining not only the life of serfs, but also their personal and religious motivations to become serfs.
