This hen goes missing repeatedly. I always think a neighbor cat got her, because she tends to go missing for days after being chased by a cat. This last time, she was gone for a week. When I put her in the back yard again, the bantams followed her around just like a woman who is worried about another one and is asking if she's okay. The RIRs chased and pecked at her. When I got home, from work, she was gone again. She actually lays eggs fairly regularly but I can't find them if she's not here. She can fly pretty well and can get from the backyard to the top of the roof, so taller fencing is not going to work. I can never see or hear her, in the neighbor's trees or on the roof.... any ideas where to look for her roost?
