Today, I tried to get her back with the flock, but it did not go well. I gave them all a big treat buffet and let her enter to share it. All was good until treats were over. 1 other hen confronted her with the whole puffed chest and feathers and they grabbed each other. I separated them immediately but the top layer of her beak was already separated and then fell off. She's back inside to see when she can eat dry feed again and then try to reintegrate. I am all ears for ideas because I had not had this issue with others who we were separated for this length of time
