Yesterday we noticed one of our hens had a swollen, large breast area. After a lot of research we determined it was likely sour crop and we are treated it with Monistat cream, ACV and probiotics in her water, dulcolax (actually Miralax),taken her off solid food, and we vomited her which brought up a bunch of brownish, nasty smelling stuff and her crop went down. However, I have attached a picture of what her breast looks like. All the feathers are gone and there seems to be a wound. She was scratching at it yesterday, so I am hoping that is what the wound is from. Is this normal for sour crop or should I be concerned about something more? The wound is toward the back where there are feathers. The top stuff is poop.
