I have 4 hens and all has been well up until now. I have a hen who wants to attack me when I'm in the backyard (Peaches). She has bit my hand and leg drawing blood. She is the smallest hen I have. We got the hens as chicks and they have turned into pets. My 13 year old daughter carries them around the yard daily so its not like they're not used to being held. I also hold them and talk to them. Why all the sudden has Peaches turned on me? I understand the pecking order and have read several posts about hens being broody when laying, but why would she take a disliking to me?

She may very well regard you as a member of the flock and is trying to subordinate you. I would not let her get away with this behavior. Press her to the ground, scoop her up in a fishing net and carry her around, let her know that you are the boss. Good luck in modifying her behavior.
