Hi I am new to posting on this forum, even though I always search it for advice! Anyway, on Friday I was out all day. I usually let my chickens free range, I have never had a problem with predators before. I came home and noticed 5 of my chickens gone, the only evidence was piles of feathers, no blood, no carcasses. I found a 6th chook hiding away and noticed she had punture wounds, was covered in saliva and had heaps of feathers missing. She passed not long after Another 6 chickens lived, but one had been slightly attacked. She had blood under her wing but it didnt look too bad, I have been checking on her quite often. 2 days after the incident I went in to check her and she had a bright green colour under her wing. Any ideas what this could be and what I should do about it? I am worried its infected but I read it could also be bruising. How could I tell if it was gangrene? Since it was a wild dog I am worried she is ill, even though she is still acting quite normal (tonight she was even on the perch with the others instead of the laying boxes like she was the previous 2 nights)... Thanks so much for reading. I am devastated and at a loss at what to do.
