So my EE Helga kicked the bucket this weekend. I had noticed she was getting thinner for a few weeks but thought maybe I was just imagining it. She also stopped "crowing" in the morning but was still laying. Friday I noticed she was really week and stumbling and her comb was pale. By Sunday she was dead (well nearly, I put her down). I NEVER saw any coughing or runny nose, so I am HOPING it was just old age. My in laws had her for four years and they told me this weekend they got her as an adult from someone else, so I am hoping she just had reached the end of her life, but I don't know. I have two banties left in the coop, one silkie and one silkie cross. They don't appear to have any symptoms and look healthy. Should I leave them there, or do I need to take other precautions?
