I have a young Rhode Island Red hen just starting to lay eggs. We have 11 other hens of varying ages and 2 roosters in our flock. We also have 6 chicks and 5 Guinea fowl. All get along fine, everyone is happy and healthy. (not sure if all that is important information but included it just in case). This particular hen is the friendliest of the bunch and follows me around, chatters and trills at me constantly. She likes to sit on me when I'm handing out treats as well. Recently she has started doing this thing where she rubs her beak back and forth on me in a side to side motion. I can't seem to find any information on this particular behavior and was wondering if it's just a funny quirk she has developed or if it means something. She looks fine, no changes in her beak appearance or anything else.
