My duck was badly injured in the Great Duck Massacre of 2016 in our yard. Our total flock was 12 and now we have 7 left. One duck has open gashes on her neck and seems to be rather alert. Immediately after the incident I tended to her first aid (I'm first aid certified), and placed her in a box. She does not do well with human contact and every time I go by the box she gets really big and hissy. I have decided her injuries are too severe to be around the other ducks and chickens (which I'm more concerned about harming her). I started her in this box yesterday and she was fine and alert this morning. I fear she may loose the want to live and I picked her up and took her out to her duck friends to look at. She did some quacking and they quacked back, but I still think her wound is too open to be around them. I would prefer it to start closing or scabbing up before letting her in the run. I have been feeding her lettuce, but I am not sure if she is eating it. I am also going to put some electrolytes in her water. She is really sensitive and she is most happy when we place a towel over her, I suspect the darkness is not the best for her which is why I am taking her on little walks every 4 hours (of me holding her). Does anyone have a suggestion for how long I may need to care for this duck in her hospital nest?
