I have three hens and until molt this Fall they have gotten along fine. Two are 2.5 years old and the third is 1.5. This was the first year the younger one molted and it seems to have changed the dynamic in the flock. During the molt she seemed pretty miserable but I wasn't concerned. I figured I was just reading human emotions into the situation. However, they are all finished molting and she still seems pretty hangdog. In fact for the last few nights she's been getting kicked out the of the coop at dusk - twice trying to sleep in the tree above the coop rather than face the other two hens. When she does make it in the coop before the door closes, there's always a kerfuffle with pecking and clucking and wings flapping. She ends up sleeping in the nesting box rather than the perch. I have two perches, one higher than the other - ladder style. They are both long enough for all three to sleep together, which they have done for over a year. Now the little one isn't allowed up there. My question is this; did the molt change something in the pecking order? Is this possible?
