Guinea with hurt wing

[Ember13]

I posted this in the guinea forum but thought chicken folks might have some experience.Guinea roosted in a tree instead of the coop. Very exposed spot. Found a pile of feathers under the tree in the a.m. Her side was all roughed up and wing is slightly dragging. She is eating and active but cannot roost. I took a photo with the part that I assume is either snapped off or dislocated. I know the picture isn't good but I figured I would try in case their is someone who really knows bird anatomy. This is the view with her wing lifted up. Any advice is welcome. I am keeping her cooped with her mate only. Access to feed and water and I built a series of low roosts in case she can manage to do short hops.
