My chickens have all been raised together. There have been issues with pecking order and a cpl bullies. I am concerned because one of my girls wont go back into the coop to roost at night and talks to us all the time when we go to check on them. She isnt missing feathers although one of my others is missing all her neck feathers. I have noticed 2 plymouth barred rocks bullying but not her. she does NOT want to be with her sisters and tends to be first out of the coop. Totally lost as to WHY this behavior
