I have a 6 month old BO hen. She went in the coop the other day and layed her egg in her favorite nest then came back outside. As she came out she started picking up leaves off the ground and trying to throw them on her back. It was like she was trying to cover her tracks of something! Has anyone else seen this happen? Is this normal or is she just a silly little BO hen? She kept doing for quite a few minutes. Just picking them up and throwing them on her back.
