Morning all. For about a week now my hen has been missing her longer tail feathers. Thought it was strange but checked her and found no wounds and everything looked great back there. She was acting fine until yesterday morning I found her sleeping alone in the doghouse in this morning sleeping alone in the nesting box. Yesterday she didn't want to be around any of the other hens. Ever since her tail feathers were missing I've been watching them when I'm home and I haven't seen anybody plucking at her or any aggression. I did notice when she came out of the doghouse yesterday morning there were a lot of feathers left behind. This morning she didn't even get up at the same time as the others to eat. She still sitting in the nesting box staring at the corner
