You know it's going to be spoiled ;) WVduckchick's advice using a towel to wipe off vaseline sounds good & allowing her/him to preen, keeps him/her busy. HOPE sounds good :weeI like MIRACLE too
As aart says set something up in the coop with the rest of your flock. Section off with wire (something sturdy & no one can get through) or wire cage (wrap with smaller wire if need), use a MHP (Blooie has a thread here) in it. This way she has the company & safety, just a thought.
Or set up...
