i have a new pycheon hen that i want to add to my phycheon flock and i have her in with some of my young d'uccles that aren't quite ready to be with a roo yet. i put the new pycheon hen in with the other 2 and the roo and the old hens wasn't happy she was there and picked and was start to get pretty mean with her. then i put in the pen right next to them so they can see her and didn't care about her one bit so i tried the next day to put her in with the pycheon roo and hens and they attacked her again. what can i do to calm the old hens so they don't go crazy when i put the new hen in? i know they need to figure out there peeking order but there were being pretty rough with her. i'm afraid they will kill her. need some help please.
