I added 2 three month silkies to my flock of 5 five month old hens. I had them separated in the coop but the worst happened and the easter egger at the bottom the the current heirichy serverly mauled one the the new girls. The back of her neck and head appear to have been pecked down the skin or worse, I don't want to hurt or stress her further. She is breathing shallowly since we seperated her. What do I do
