Chicken Ostracized Update

[JoCin]

Hi Everyone, I posted several weeks ago and its been about 2 months since my flock of 6 Cinnamon Queens (all the same age) began to ostracize one chicken. We have tried several behavior modification techniques, with little success. To update, the 5 have not drawn blood on #6. They will allow her to lay her egg in the coop and roost at night, but during the day she is ostracized from them and they guard the food and water. I have added additional waterers and make sure she is getting food and water. Does anyone have any experience as to whether this behavior will eventually subside? Thanks.
