Ok, so this isn't a real disease. But I was reading on here that several hens (including one of my own) have suddenly become sluggish and listless, stopped eating/drinking without any other symptoms, and several have died. Another commonality is that this issue doesn't seem to spread in the flock with only one or two birds affected. In my case at least, worms and mites are not an issue. This is just an observation that whatever this issue is , it seems to be prevalent across the country and with several hens (seems to always be hens) in our forum. Who else has noticed these symptoms and does anyone have any ideas?
