Can I introduce Lonely, our only remaining chicken

She was not always called Lonely, she used to be called Grumpy or Devil Bird or other things Blippers ears should not hear.
Her temperament has improved since she has become an only chick but she is subject to becoming broody. She is doing it again now (just look at her face). So no eggs for a while.
We have tried lots of the suggested remedies, last time she had 4 days in Hen Jail (another coop). It is difficult to keep her segregated or solitary confinement when there is only her.
Although she is grumpy and moody and old she is still a very good looking bird.
