my silkie chicken (silkie) has something under her wing and I don't know what it is we did have a dog attack our chickens but she was fine I really don't know she's a nice girl I really don't want her to die but here is a picture anything helps thanks!
It doesn't look super red and infected, does it feel warm? It looks like it is healing up so I wouldn't worry too much unless I'm not seeing something. I would think about disinfecting it with something maybe.
