I need advice, one of my Auracanas collapsed this morning. I had to get a symptom report over the phone, crop is mushy, feet are cold, as of yesterday evening she had no visible symptoms. She made it out of the coop, but collapsed in the ten minutes between the coop door opening and food bowls being filled. Other than some peck marks from the other birds, she doesn't have any ruffled feathers or blood. She's still breathing, and complained at being picked up, but is limp to the point of dirt in her eye. The only thing I can possibly think of is botulism, but everything's frozen solid and they're kept in a confined run. Anyone else faced this? What can I do?
